To investigate functions of the consensus amino terminus of G protein-coupled receptor kinases (GRKs), two amino terminus-truncated mutants (delta30 or delta15) and two single-amino-acid mutants of conserved acidic residues (D2A or E7A) of human GRK1 were constructed and expressed in human embryonic kidney 293 cells. It was shown that truncated mutations(More)
Human rhodopsin kinase (RK) and a carboxyl terminus-truncated mutant RK lacking the last 59 amino acids (RKC) were expressed in human embryonic kidney 293 cells to investigate the role of the carboxyl terminus of RK in recognition and phosphorylation of rhodopsin. RKC, like the wild-type RK, was detected in both plasma membranes and cytosolic fractions. The(More)
