Anti-GM2AP antibodies enable researchers to detect and measure the GM2AP antigen in biological samples. This target is a reported synonym of the GM2A gene, which encodes ganglioside GM2 activator. This protein is known to function in the metabolism of lipids, among other biological roles. The human version of GM2AP has a canonical amino acid length of 193 residues and a protein mass of 20.8 kilodaltons. It is reported to be localized in the lysosomes of cells and widely expressed in many tissue types.
