Anti-PKAcb antibodies enable researchers to detect and measure the PKAcb antigen in biological samples. This target is a reported synonym of the PRKACB gene, which encodes protein kinase cAMP-activated catalytic subunit beta. This protein is known to function in peptidyl-serine phosphorylation and protein phosphorylation, among other biological roles. The human version of PKAcb has a canonical amino acid length of 351 residues and a protein mass of 40.6 kilodaltons. It is reported to be localized in the cell membrane, nucleus, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include CAFD2 and PKA C-beta. Some PKAcb antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
