Comments
  • 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; self-associates in the presence of lysolipid.
  • INTERACTION:
    O64682:At2g34650 (xeno); NbExp=1; IntAct=EBI-908215, EBI-1393382;
    P28482:MAPK1 (xeno); NbExp=1; IntAct=EBI-908215, EBI-959949;
  • SUBCELLULAR LOCATION: Myelin membrane; Peripheral membrane protein; Cytoplasmic side. Note=Cytoplasmic side of myelin.
  • TISSUE SPECIFICITY: Found in both the central and the peripheral nervous system.
  • PTM: At least 6 charge isomers; C1 (the most cationic and least modified form), C2, C3, C4, C5 and C6 (the least cationic form); are produced as a result of optional post-translatonial modifications, such as phosphorylation of serine or threonine residues, deamidation of glutamine or asparagine residues, citrullination and methylation of arginine residues.
  • SIMILARITY: Belongs to the myelin basic protein family.
