Oligodendrocyte Marker
The classic group of Myelin basic protein (MBP) isoforms (isoforms 4 to 14) are with PLP the most abundant protein components of the myelin membrane in the CNS. They have a role in both its formation and stabilization. The smaller isoforms might have an important role in remyelination of denuded axons in multiple sclerosis. The non classic group of MBP isoforms (isoforms 1 to 3/Golli MBPs) may preferentially have a role in the early developing brain long before myelination, maybe as components of transcriptional complexes, and may also be involved in signaling pathways in T cells and neural cells. Differential splicing events combined to optional posttranslational modifications give a wide spectrum of isomers, each of them having maybe a specialized function.
Function:
The classic group of MBP isoforms (isoform 4-isoform 14) are with PLP the most abundant protein components of the myelin membrane in the CNS. They have a role in both its formation and stabilization. The smaller isoforms might have an important role in remyelination of denuded axons in multiple sclerosis. The non-classic group of MBP isoforms (isoform 1-isoform 3/Golli-MBPs) may preferentially have a role in the early developing brain long before myelination, maybe as components of transcriptional complexes, and may also be involved in signaling pathways in T-cells and neural cells. Differential splicing events combined with optional post-translational modifications give a wide spectrum of isomers, with each of them potentially having a specialized function. Induces T-cell proliferation.
Subunit:
Homodimer. Isoform 3 exists as a homodimer.
Subcellular Location:
Myelin membrane; Peripheral membrane protein; Cytoplasmic side. Note=Cytoplasmic side of myelin.
Tissue Specificity:
MBP isoforms are found in both the central and the peripheral nervous system, whereas Golli-MBP isoforms are expressed in fetal thymus, spleen and spinal cord, as well as in cell lines derived from the immune system.
Post-translational modifications:
Several charge isomers of MBP; C1 (the most cationic, least modified, and most abundant form), C2, C3, C4, C5, C6, C7, C8-A and C8-B (the least cationic form); are produced as a result of optional PTM, such as phosphorylation, deamidation of glutamine or asparagine, arginine citrullination and methylation. C8-A and C8-B contain each two mass isoforms termed C8-A(H), C8-A(L), C8-B(H) and C8-B(L), (H) standing for higher and (L) for lower molecular weight. C3, C4 and C5 are phosphorylated. The ratio of methylated arginine residues decreases during aging, making the protein more cationic.
The N-terminal alanine is acetylated (isoform 3, isoform 4, isoform 5 and isoform 6).
Arg-241 was found to be 6% monomethylated and 60% symmetrically dimethylated.
Phosphorylated by TAOK2, VRK2, MAPK11, MAPK12, MAPK14 and MINK1.
Similarity:
Belongs to the myelin basic protein family.

phospho-MBP(Tyr203)抗体（antibody,
Ab）是由效应B细胞（效应**B细胞）分泌，机体用于抵御外来物质，如病毒，**等抗原，结构呈“Y”字型的球状蛋白质，仅仅存在于脊椎动物的血液和B**细胞膜表面。凡是能够跟抗体结合的物质，均被称作抗原，因此对于抗抗体（能够结合抗体的抗体）来说，抗体本身也是一种抗原物质。
phospho-MBP(Tyr203)抗体普通抗体重链和轻链的结构
重链结构：普通的**球蛋白具有2条重链（H链），分子量约为50kD,有μ、δ、γ、ε和α五种重链亚型，对应的**球蛋白名称分别为IgM、IgG、IgA、IgD和IgE。
轻链结构： 普通**球蛋白具有2条轻链（L链），分子质量约25kDa，有κ链和λ链两种亚型，这两种轻链决定了Ig的亚型类别（IgG1，IgG2，IgG3，IgG4）。一个天然的Ig分子两条轻链总是相同的，但在同一个体内可存在分别带有κ或λ链的抗体分子。不同种属生物体内两型轻链的比例不同，正常人血清**球蛋白κ链：λ链约为2：1，而在小鼠的比例为20：1。
2.2抗体Fab段和Fc段
IgG经木瓜蛋白酶酶切后裂解为2个完全相同的Fab段和1个Fc段,每个Fab段都为单价,可与抗原结合但不会再发生凝集反应；经胃蛋白酶酶切后裂解为1个完整F(ab)2片段和碎片化的Fc片段,F(ab’)2片段为双价,可同时结合两个抗原表位。Fab段为抗原结合片段（fragment of antigen binding，Fab），相当于抗体分子的两个臂，由一个完整的轻链和重链的VH和CH1结构域组成。Fc段为可结晶段（fragment crystallizable，Fc）相当于Ig的CH2和CH3结构域，是Ig与效应分子或者细胞相互作用的部位。Fab段包含完整的可变区，以及恒定区的CH1区域。Fc段仅指Ig恒定区CH2和CH3的区域，相当于Y字结构下面那一部分。
