Anti-misato mitochondrial distribution and morphology regulator 1 antibodies are used for the immunodetection of the protein encoded by the MSTO1 gene. In humans, the canonical protein has a reported length of 570 amino acid residues and a mass of 61.8 kDa. Its subcellular localization is in the mitochondria and cytoplasm. Alternative splicing is reported to yield 7 different isoforms for this protein. A member of the Misato protein family, it is reported to be involved in regulation of mitochondrial distribution and morphology. The gene encoding this protein is implicated in Myopathy, mitochondrial, and ataxia. Other names for this target antigen include MMYAT, MST, protein misato homolog 1, misato 1, mitochondrial distribution and morphology regulator, misato homolog 1, and LST005. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
