背景

The protein encoded by the classic MBP gene is a major constituent of the myelin sheath of oligodendrocytes and Schwann cells in the nervous system. However, MBP-related transcripts are also present in the bone marrow and the immune system. These mRNAs arise from the long MBP gene (otherwise called "Golli-MBP") that contains 3 additional exons located upstream of the classic MBP exons. Alternative splicing from the Golli and the MBP transcription start sites gives rise to 2 sets of MBP-related transcripts and gene products. The Golli mRNAs contain 3 exons unique to Golli-MBP, spliced in-frame to 1 or more MBP exons. They encode hybrid proteins that have N-terminal Golli aa sequence linked to MBP aa sequence. The second family of transcripts contain only MBP exons and produce the well characterized myelin basic proteins. This complex gene structure is conserved among species suggesting that the MBP transcription unit is an integral part of the Golli transcription unit and that this arrangement is important for the function and/or regulation of these genes.

6. 复温

4℃孵育过夜后,室温下复温15 min (若在室温下孵育一抗,则直接进入下一步清洗);用PBS洗涤5 min,重复3次。

7. 二抗孵育

用吸水纸吸玻片上多余的液体,加入2-4HRP标记羊抗IgG工作液(试剂6,置于湿盒中,37℃孵育1-2 h;用PBS洗涤5 min,重复3

8. 显色

用吸水纸吸去玻片上多余的液体,在每张切片上滴加约50 μL新配制的DAB工作液(试剂7:试剂8:PBS=1:1:18,作用3-5 min。显微镜下观察结果,达到合适的显色强度后,用蒸馏水冲洗切片以终止反应,用蒸馏水冲洗5 min,重复3次。

9. 复染

滴加适量复染试剂(试剂9复染3-5 min,蒸馏水冲洗5 min,滴加盐酸酒精分化约30 s,蒸馏水洗涤5 min,重复2次。

10. 脱水封片

将玻片依次置于不同浓度(70%80%90%95%100%)乙醇,各5 min;然后置于新鲜二甲苯中浸泡脱蜡3,每次15 min。用吸水纸吸去多余的二甲苯,滴加适量封片剂(试剂10在组织上,将盖玻片盖在组织上,避免产生气泡。


注意事项

1. 建议检测时进行阴性及阳性对照,以提高实验的可靠性。

2. 本品中的配套试剂,请不要用其他生产商产品替换使用。

3. DAB为致癌物质,请采取必要的防范措施。

4. PBS洗涤液(试剂1)配制后在4℃可保存一周;抗原修复液(试剂2)及显色剂(试剂78)的工作液需每次实验时现用现配。

背景资料
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.

靶标

基因名
MBP
蛋白名
Myelin basic protein
亚基
Homodimer. Isoform 3 exists as a homodimer.
亚细胞定位
Myelin membrane; Peripheral membrane protein; Cytoplasmic side. Note=Cytoplasmic side of myelin.
组织特异性
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.
翻译后修饰
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.
相似性
Belongs to the myelin basic protein family.
功能
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.
