Myelin basic protein is a multifunctional protein whose primary role is to adhere membranes of the myelin sheath. There are various isoforms that have been identified, 6 distinct isoforms in human and 13 distinct isoforms in mice. These distinct isoforms are the product of alternative splicing of a single gene. The present study sought out to identify the different isoforms found in the murine central nervous system. Neuronal tissue (brain) from five different C57BL6/J mice at 2 months of age was harvested and used for mRNA extraction. mRNA was reversed transcribed to cDNA and transcripts were detected through PCR amplification and DNA agarose gel separation. Primers for exon 1, exon 5b and exon 11 of the myelin basic protein gene were used to capture all the possible transcripts that are naturally found in the murine central nervous system. Unknown transcript was sequenced at Genewiz facilities (South Plainfield, NJ) and mass spectrometry protein sequence analysis demonstrated the presence of a novel myelin basic protein transcript variant. We identified a novel transcript variant of myelin basic protein. This novel transcript variant corresponds to a myelin basic protein of 32.5 kDa which has not been previously reported. This novel transcript variant presents relevant clinical significance to various demyelinating diseases due to its contribution to the understanding of the natural state of the murine central nervous system.
