Beschreibung:   Galectin 3 is a lectin with carbohydrate recognition domains (CRD) which bind  -galactoside. It is a multifunctional protein expressed both on the cell surface, cytoplasm and nucleus and appears to have roles in specific carbohydrate binding and in the regulation of mRNA splicing.

Beschreibung:   The heat shock proteins were discovered, as the name suggests, since they are heavily upregulated when cells are stressed by temperatures above the normal physiological range. They are expressed in unstressed cells also and have a normal function as chaperones, helping other proteins to fold correctly, and are required in much greater amounts if the cell or tissue is stressed by heat. The increased levels are generated transcriptionally under the influence of a powerful transcription factor, the heat shock factor 1 (HSF1). The different heat shock proteins were originally named based on their SDS-PAGE mobility, so HSP27 has an apparent molecular weight of 27kDa. It is an abundant protein even under non-stress conditions and frequently shows up as a major spot on 2 dimensional gels of cells or tissues. It is known to associate with a variety of other proteins such as actin, intermediate filament subunits and ubiquitin and is found both in the cytoplasm and the nucleus of cells. HSP27 can become heavily phosphorylated under the influence of multiple protein kinases particularly as a result of activation of the p38/SAPK pathway. Upregulation of this protein is protective against neurodegenerative diseases at least in certain mouse models (1). Point mutations in the HSP27 gene are associated with two neurological diseases, Charcot-Marie-Tooth disease type 2F and distal hereditary motor neuropathy IIB (2). These diseases are associated with axonal loss apparently following defects in the transport of neurofilaments.

Beschreibung:   May be involved in the regulation of dopamine release and transport. Induces fibrillization of microtubule-associated protein tau. Reduces neuronal responsiveness to various apoptotic stimuli, leading to a decreased caspase-3 activation. Ref: uniprot.org.

Beschreibung:   Saporin is a ribosome-inactivating protein (RIP) of type I. This monomeric RNA N-glycosidase purified from seeds of the plant Saponaria officinalis also known as Soapwort, is capable of specific depurination of eukaryotic ribosomes thus arresting protein synthesis. No ligand has been identified in saporin hence its inability to transverse the cell membrane. Due to its toxicity and stability of the structure, saporin has proven extremely useful for construction of immunotoxins.

Beschreibung:   CNTF is a survival promoting factor for different types of neurons in vitro and in vivo. The essential structural features for the biological function of human CNTF were investigated by Thier, M. et al. They showed that deletion of 14 N-terminal and 18 C-terminal amino acids significantly increased bioactivity compared to wild-type CNTF. FUNCTION: CNTF is a survival factor for various neuronal cell types. Seems to prevent the degeneration of motor axons after axotomy. SUBUNIT: Homodimer. SUBCELLULAR LOCATION: Cytoplasm. TISSUE SPECIFICITY: Nervous system. PHARMACEUTICAL: CNTF is being tested under the name Axokine by Regeneron Pharmaceuticals for treatment of human motor neuron diseases, such as amyotrophic lateral sclerosis (ALS). As it induces substantial weight loss, preferentially of fat as opposed to lean body mass, it is being used for obesity treatment. SIMILARITY: Belongs to the CNTF family.

Beschreibung:   FUNCTION: This is a receptor for the tachykinin neuropeptide neuromedin K (neurokinin B). It is associated with G proteins that activate a phosphatidylinositol-calcium second messenger system. SUBCELLULAR LOCATION: Membrane; multi-pass membrane protein. PTM: The anchoring of this receptor to the plasma membrane is probably mediated by the palmitoylation of a cysteine residue. MISCELLANEOUS: The rank order of affinity of this receptor to tachykinins is: neuromedin K > substance K > substance P. SIMILARITY: Belongs to the G-protein coupled receptor 1 family.

Beschreibung:   Receptor tyrosine kinase involved in nervous system and probably heart development. Upon binding of its ligand NTF3/neurotrophin-3, NTRK3 autophosphorylates and activates different signaling pathways, including the phosphatidylinositol 3-kinase/AKT and the MAPK pathways, that control cell survival and differentiation (Ref: uniprot.org).

Beschreibung:   FUNCTION: Functions as an E1 enzyme essential for multisubstrates such as GABARAPL1 and ATG12. Forms intermediate conjugates with GABARAPL1 (GABARAPL2, GABARAP or MAP1ALC3). Formation of the final GABARAPL1-PE conjugate is essential for autophagy. SUBUNIT: Homodimer (By similarity). Interacts with ATG3 and ATG12. The complex, composed of ATG3 and ATG7, plays a role in the conjugation of ATG12 to ATG5. SUBCELLULAR LOCATION: Cytoplasm (Probable). ALTERNATIVE PRODUCTS: 2 named isoforms produced by alternative splicing. TISSUE SPECIFICITY: Widely expressed, especially in kidney, liver, lymph nodes and bone marrow. DOMAIN: The C-terminal part of the protein is essential for the dimerization and interaction with ATG3 and ATG12. SIMILARITY: Belongs to the ATG7 family. In yeast, ATG7 appears to be required for fusion of peroxisomal and vaculuolar membranes.

Beschreibung:   BDNF belongs to the neurotrophin family and promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. It is a major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. Microglia release BDNF that may contribute to neuroinflammation and neuropathic pain. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. Post translation modification: Converted into mature BDNF by plasmin (PLG). SIMILARITY: Belongs to the NGF-beta family.

Beschreibung:   FUNCTION: Can mediate activation of c-Jun and NF-kappa-B. May promote caspase-independent cell death. Isoform 2 and isoform 3 may act as decoy receptors. SUBUNIT: Associates with TRAF1, TRAF2, TRAF3 and TRAF5. SUBCELLULAR LOCATION: Isoform 1, isoform 3, isoform 4: Cell membrane; single-pass type I membrane protein (Probable). Isoform 2: Secreted protein (Probable). ALTERNATIVE PRODUCTS: 4 named isoforms produced by alternative splicing. TISSUE SPECIFICITY: Highly expressed in adult brain, and in embryos from day 11-17, but not earlier. Detected in embryonic brain and epithelium, and at lower levels in adult heart, lung and liver. In neonatal mice, mainly in hair follicles and neuron-like cells in the cerebellum, but not in the skin epidermis. Isoform 3 was found in embryonic day 17.5 skin but not in brain and liver. SIMILARITY: Contains 3 TNFR-Cys repeats.

Beschreibung:   FUNCTION: Nerve growth factor is important for the development and maintenance of the sympathetic and sensory nervous systems. It stimulates division and differentiation of sympathetic and embryonic sensory neurons. SUBUNIT: Homodimer, associated by noncovalent forces. SUBCELLULAR LOCATION: Secreted protein. SIMILARITY: Belongs to the NGF-beta family.

Beschreibung:   Ghrelin is the ligand for growth hormone secretagogue receptor type 1 (GHSR) and upon binding to the receptor it induces the release of growth hormone from the pituitary. This ligand has an appetite-stimulating effect and is involved in growth regulation (Ref: SWISSPROT).

Beschreibung:   Myelin is a membrane characteristic of the nervous tissue and functions as an insulator to increase the velocity of the stimuli being transmitted between a nerve cell body and its target. Myelin isolated from human and bovine nervous tissue is composed of approximately 80% lipid and 20% protein, and 30% of the protein fraction constitutes myelin basic protein (MBP). MBP is an 'intrinsically unstructured' protein with a high proportion (approximately 75%) of random coil, but postulated to have core elements of beta-sheet and alpha-helix. MBP is a major protein in CNS myelin and is expressed specifically in the nervous system. A detailed immunochemical examination of monoclonal and polyclonal antibody responses to MBP and its peptides has revealed the existence of as many as 27 antigenic determinants, many of them conformational. Topological mapping of the potential antigenic determinants onto a model of MBP secondary structure places these determinants within 11 separate regions of the molecule, including those portions that have been found to be encephalitogenic. The message for myelin basic protein is selectively translocated to the ends of the cell processes. Immunization with myelin-associated antigens including MBP significantly promotes recovery after spinal cord contusion injury in the rat model. FUNCTION: Is, with PLP, the most abundant protein component of the myelin membrane in the CNS. Has a role in both the formation and stabilization of this compact multilayer arrangement of bilayers. Each splice variant and charge isomer may have a specialized function in the assembly of an optimized, biochemically functional myelin membrane (By similarity). SUBUNIT: Homodimer (By similarity). SUBCELLULAR LOCATION: Myelin membrane; peripheral membrane protein; cytoplasmic side. Cytoplasmic side of myelin. TISSUE SPECIFICITY: Found in both the central and the peripheral nervous system. PTM: At least 5 charge isomers; C1 (the most cationic, least modified, and most abundant form), C2, C3, C4 and C5 (the least cationic form); are produced as a result of optional posttranslational modifications such as phosphorylation of serine or threonine residues, deamidation of glutamine or asparagine residues, citrullination and methylation of arginine residues. C1 and C2 are unphosphorylated, C3 and C4 are monophosphorylated and C5 is phosphorylated at two positions. SIMILARITY: Belongs to the myelin basic protein family.
