Anti-PRKAA antibodies enable researchers to detect and measure the PRKAA antigen in biological samples. This target is a reported synonym of the PRKAA2 gene, which encodes protein kinase AMP-activated catalytic subunit alpha 2. This protein is known to function in autophagy pathways and carbohydrate metabolism and homeostasis, among other biological roles. The human version of PRKAA has a canonical amino acid length of 552 residues and a protein mass of 62.3 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the kidney, heart muscle, fallopian tube, cerebral cortex, and cerebellum. Other names for this target antigen include AMPK, AMPK2, and AMPKa2. Western Blot is the most common application for the PRKAA antibodies listed below. ELISA and Immunohistochemistry are also common applications.
