Anti-PHKA1 antibodies are used in the immunodetection of the protein phosphorylase kinase regulatory subunit alpha 1. In humans, the canonical protein has a reported length of 1223 amino acid residues and a mass of 137.3 kDa. Its subcellular localization is in the cell membrane. Up to 3 different isoforms have been reported for this protein. It is reported to have muscle specific expression. A member of the Phosphorylase b kinase regulatory chain protein family, PHKA1 is known to be involved with metabolic processes. Synonyms for this target antigen include phosphorylase b kinase regulatory subunit alpha, skeletal muscle isoform, phosphorylase kinase alpha M subunit, phosphorylase kinase, alpha 1 (muscle), muscle glycogenosis, and PHKA. PHKA1 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. A number of PHKA1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
