The PYK ELISA kits listed below are analytical tools for measuring concentrations of PYK in various samples. PYK is an alternative name for the human PHKA2 gene, which encodes the protein, phosphorylase kinase regulatory subunit alpha 2. It has been mentioned that PYK plays a role in carbohydrate metabolism and homeostasis, among other functions. Structurally, the PHKA2 protein is described to be 1235 amino acid residues in length and 138.4 kilodaltons in mass. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is reported to be highly expressed in the liver and other non-muscle tissues. Other names for this target antigen include GSD9A and PHK.
