Anti-phosphoglycerate mutase 2 (muscle) antibodies enable researchers to detect and measure the phosphoglycerate mutase 2 (muscle) antigen in biological samples. This target is a reported synonym of the PGAM2 gene, which encodes phosphoglycerate mutase 2. This protein is known to function in the Notch signaling pathway and spermatogenesis, among other biological roles. The human version of phosphoglycerate mutase 2 (muscle) has a canonical amino acid length of 253 residues and a protein mass of 28.8 kilodaltons. It is reported to be notably expressed in the testis, skeletal muscle, and heart muscle. Other names for this target antigen include GSD10, PGAM-M, and PGAMM.
