Anti-memA antibodies enable researchers to detect and measure the memA antigen in biological samples. This target is a reported synonym of the PNN gene, which encodes pinin, desmosome associated protein. This protein is known to function in cell adhesion and RNA splicing, among other biological roles. The human version of memA has a canonical amino acid length of 717 residues and a protein mass of 81.6 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include DRS, DRSP, and SDK3.
