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.

A study in Sprague Dawley rats demonstrated that adolescent morphine exposure in females caused transgenerational attenuation of morphine self-administration in offspring, with RNA sequencing and qPCR analysis showing the MBP was downregulated in the nucleus accumbens of both male and female F1 generation rats and exhibited sex-specific dysregulation in the F2 generation [Fair M. Vassoler et al. DOI:10.1016/j.neuropharm.2016.10.006]. A separate review on traumatic brain injury (TBI) in humans, rats, and mice identified the MBP as a protein biomarker of brain damage that can be measured in serum and cerebrospinal fluid to evaluate injury severity and correlate with morbidity and mortality [Annunziato Mangiola et al. DOI:10.1155/2015/736104].
