Anti-GPRK1 antibodies enable researchers to detect and measure the GPRK1 antigen in biological samples. This target is a reported synonym of the GRK1 gene, which encodes G protein-coupled receptor kinase 1. This protein is known to function in protein phosphorylation, among other biological roles. The human version of GPRK1 has a canonical amino acid length of 563 residues and a protein mass of 63.5 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the retina. Other names for this target antigen include RHOK and RK. Western Blot is the most common application for the GPRK1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
