Anti-Myelin Basic Protein MBP Monoclonal Antibody

In the embryo, isoform 1-isoform 3 are found in neurons within the central nervous system (primarily in pioneer neurons important in the formation of the cortex) and the peripheral nervous system. They are also expressed in the thymus, gut, lung and kidney. In the adult, isoform 1-isoform 3 are highly expressed in the brain (mainly in brain regions rich in oligodendrocytes) and spleen. Lower levels are seen in the heart, kidney and lung. Isoform 2 is also found in cells of the immune system. The isoforms missing the 134 first amino acids (isoform 4- isoform 13) are almost exclusively produced in the myelin-forming cells, the mature oligodendrocytes.

The classic group of MBP isoforms (isoform 4-isoform 13) 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 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 to optional post-translational modifications give a wide spectrum of isomers, with each of them potentially having a specialized function. .
