Anti-Atp6m antibodies enable researchers to detect and measure the Atp6m antigen in biological samples. This target is a reported synonym of the ATP6V1D gene, which encodes ATPase H+ transporting V1 subunit D. This protein is known to function in cilium assembly and autophagy pathways, among other biological roles. The human version of Atp6m has a canonical amino acid length of 247 residues and a protein mass of 28.3 kilodaltons. It is reported to be localized in the membrane, cytoplasmic vesicles, and cytoplasm of cells and notably expressed in the pancreas, kidney, hippocampus, cerebral cortex, and cerebellum. Other names for this target antigen include VATD and VMA8.
