This gene encodes a member of the globin superfamily and is predominantly expressed in skeletal and cardiac muscles. The encoded protein forms a monomeric globular haemoprotein that is primarily responsible for the storage and facilitated transfer of oxygen from the cell membrane to the mitochondria. This protein also plays a role in regulating physiological levels of nitric oxide. Multiple transcript variants encoding distinct isoforms exist for this gene. [provided by RefSeq, May 2020]
A study in human brain tissue demonstrated that the MB mRNA, selected for investigation due to its distinct upregulation in the cerebellar region, could not be reliably and repeatedly detected in any of the four forensically relevant cerebral cortex lobes (frontal, temporal, parietal, occipital) via multiplex-RT-PCR and capillary electrophoresis [Euteneuer et al. DOI:10.1007/s12024-024-00787-7].
