- 说明书：
Full-length recombinant human GRK7 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. The gene accession number is NM_139209.
GRK7 is a member of the G protein-coupled receptor kinase subfamily and is a Ser/Thr protein kinase. GRK7 is specifically expressed in the retina and has been shown to phosphorylate cone opsins and initiate their deactivation (1). GRK7 catalyzes rhodopsin phosphorylation in a light-dependent manner. GRK7 co-localizes with GRK1 in human cone outer segments. PKA phosphorylates GRK7 at Ser(23) and Ser(36) in vitro and phosphorylation of GRK7 by PKA reduces the ability of GRK7 to phosphorylate rhodopsin in vitro (2). Since exposure to light causes a decrease in cAMP levels in rod cells, it is proposed that phosphorylation of GRK7 by PKA occurs in the dark.
