Anti-Vma5 antibodies enable researchers to detect and measure the Vma5 antigen in biological samples. This target is a reported synonym of the ATP6V1C1 gene, which encodes ATPase H+ transporting V1 subunit C1. This protein is known to function in autophagy pathways, among other biological roles. The human version of Vma5 has a canonical amino acid length of 382 residues and a protein mass of 43.9 kilodaltons. It is reported to be localized in the cytoplasmic vesicles and membrane of cells and widely expressed in many tissue types. Vma5 is a member of the V-ATPase C subunit protein family.
