CATEGORY

structural protein

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm
	intracellular,nucleus

basic FUNCTION	playing a role in nerve function and in formation and stabilization of the myelin membrane
	may play a role in regulating the deposition of Abeta42 and thereby also may regulate the early formation of amyloid plaques in Alzheimer's disease (Hoos 2009)
	play roles in myelination and T cell activation pathways (Ahmed 2007)
	acting synergistically with PMP2 to cause stacking of lipid bilayers (Suresh 2010)
	function as a new type of modulator of intracellular Ca(2+) levels in oligodendrocyte progenitor cells (OPCs)
	the only known structural protein required for formation of myelin, produced by oligodendrocytes in the central nervous system, is myelin basic protein (MBP)

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

development , immunity/defense , nervous system

text	central nervous system development

PATHWAY

metabolism

synaptic transmission

a component

major constituent of normal myelin of central nervous system

INTERACTION

DNA

RNA

small molecule

protein	specific interaction between HSPA4 and MBP suggestive of a possible role for HSPA4 in the immunopathology associated with multiple sclerosis (Lund 2006)
	interacting with OLIG1 and SOX10 (OLIG1 and SOX10 interact synergistically to drive myelin basic protein transcription in oligodendrocytes) (Li 2007)
	interaction of calmodulin with a C-terminal segment of MBP (Majava 2008)
	regulates SOCE (store-operated Ca(2+) entry) in T-cells and oligodendrocyte precursor cells
	binds to STIM1-ORAI1 complexes to negatively regulate the activity of SOCCs (store-operated Ca(2+) channels)
	RNA-binding protein HNRNPF is a novel component of MBP mRNA transport granules
	HNRNPF is a regulatory element of MBP expression in oligodendrocytes, suggesting an important function of HNRNPF in the control of myelin synthesis
	DDX54 may directly interact with MBP mRNA
