Anti-ATPase, H+ transporting, lysosomal 31kDa, V1 subunit E2 antibodies enable researchers to detect and measure the ATPase, H+ transporting, lysosomal 31kDa, V1 subunit E2 antigen in biological samples. This target is a reported synonym of the ATP6V1E2 gene, which encodes ATPase H+ transporting V1 subunit E2. This protein is known to function in autophagy pathways, among other biological roles. The human version of ATPase, H+ transporting, lysosomal 31kDa, V1 subunit E2 has a canonical amino acid length of 226 residues and a protein mass of 26.1 kilodaltons. It is reported to be notably expressed in the testis. Other names for this target antigen include V-type proton ATPase subunit E 2 and ATPase, H+ transporting, lysosomal 31kDa, V1 subunit E2.
