GRK1 Antibody (MA1-720) in ICC/IF

Immunofluorescence analysis of Rhodopsin Kinase 1a was done on 70% confluent log phase MCF-7 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Rhodopsin Kinase 1a (G8) Mouse Monoclonal Antibody (Product # MA1-720) at 2 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjuga...

GRK1 Antibody — Figure 2 Protein expression in wild-type, Arr1 +/- , GRK1 +/- , and GRK1 +/- Arr1 +/- rods. (A) Representative immublot analysis of arrestin and GRK1 expression in retinas of wild-type and heterozygous knockout mice. The blot was probed with polyclonal anti-arrestin, monoclonal anti-rhododopsin kinase 1a, and monoclonal anti- beta tubulin antibodies. Two different dilutions of the same samples were run on the same blot. (B) Levels of arrestin1 and GRK1 expression in heterozygous knockout retinas normalized to the levels in wild-type retinas. Integrated fluorescence intensity values were used for all analyses. Variations in sample loading were corrected for by normalizing the intensity value of each protein band to the intensity value of beta -tubulin in the same lane. Open circles and triangles show the results from two different dilutions. Normalized ratios of arrestin1 and GRK1 expression compared to wild-type values for Arr1 +/- were 0.34 +- 0.06 and 0.87 +- 0.07 (mean +- SEM, n = 5); 1.14 +- 0.10 and 0.32 +- 0.03 for GRK1 +/- (n = 4); and 0.54 +- 0.09 and 0.34 +- 0.03 for GRK1 +/- Arr1 +/- (n = 5). (C) Levels of PDE alphabeta , PDE gamma and RGS9-1 expression in heterozygous retinas normalized to the levels in wild-type retinas. Normalized ratios of PDE alphabeta , PDE gamma and RGS9-1 compared to wild-type values for Arr1 +/- were 0.97 +- 0.03, 1.06 +- 0.05, and 1.05 +- 0.07 (n = 4); 0.86 +- 0.03, 0.99 +- 0.04, and 1.05 +- 0.07 for GRK1 +/- (n = 4); 0.89 +- 0.05, 0.99 +- {KO}

Product Specific Information

MA1-720 detects G-protein-associated rhodopsin kinase 1a (GRK1a) from human, mouse, rat, bovine and chicken tissues.

MA1-720 has been successfully used in Western blot, immunofluorescence and immunoprecipitation procedures. By Western blot, this antibody detects an ~60 kDa protein representing GRK1a from bovine rod outer segments. Immunofluorescence staining of GRK1a in bovine retina with MA1-720 results in intense staining primarily in cone outer segments, but also in rod outer segments. Weak staining is observed in somata and synaptic terminals of cones and inner segments of rods.

The MA1-720 immunogen is full length human GRK1. This antibody recognizes an epitope in the C-terminal region of GRK1a.

Target Information

GRK1 is a member of the guanine nucleotide-binding protein (G protein)-coupled receptor kinase subfamily of the Ser/Thr protein kinases. GRK1 mediates rapid desensitization of rod photoreceptors to light by catalyzing phosphorylation of the visual pigment rhodopsin which leads to its deactivation. Defects in GRK1 are known to cause Oguchi disease 2 (also known as stationary night blindness Oguchi type-2). GRK1 can be phosphorylated by PKA and this reduces the ability of GRK1 to phosphorylate rhodopsin in vitro. It is speculated that phosphorylation of GRK1 by PKA in vivo occurs in the dark when cAMP levels in photoreceptor cells are elevated.
