Anti-YME1 like 1 ATPase antibodies are used in the immunodetection of the protein encoded by the YME1L1 gene. In humans, the canonical protein has a reported length of 773 amino acid residues and a mass of 86.5 kDa. Its subcellular localization is in the mitochondria. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported be highly expressed in cardiac and skeletal muscle mitochondria. A member of the AAA ATPase protein family; Peptidase M41 protein family, it is reported to be an ATP-dependent metalloprotease that catalyzes the degradation of folded and unfolded proteins with a suitable degron sequence in the mitochondrial intermembrane region. Post-translational modifications have been described, including protein cleavage. Other names for this target antigen include MEG4, OPA11, PAMP, YME1L, ATP-dependent zinc metalloprotease YME1L1, and FTSH.
