| Popis: | We have screened genes predominantly expressed in the rat spinal cord, and we report here cloning of the most abundant unknown gene. It is a novel member of the central nervous system (CNS) myelin-constituting proteins, myelin-associated oligodendrocytic basic protein (MOBP). MOBP is abundantly expressed specifically in oligodendrocytes at the mRNA level only next to myelin basic protein (MBP) and proteolipid protein. Two isoforms have been confirmed. One of them has proline-rich tandem repeats and has 84% homology with human counterpart in terms of predicted amino acid sequences. The cDNA-derived primary structure predicts a small, soluble, basic protein. The immunoelectron microscopy has shown that MOBP is expressed throughout compact myelin. All these characteristics are similar to MBP. One definite difference between MBP and MOBP is that MOBP is expressed exclusively in the CNS myelin. These findings suggest that MOBP shares some important functions with MBP in the CNS myelin such as myelin compaction. |
