Scientific Data

Western Blot Detection of Human GRK3 antibody by Western Blot. View Larger

Detection of Human GRK3 by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line and CEM human T-lymphoblastoid cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human GRK3 Monoclonal Antibody (Catalog # MAB47851) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for GRK3 at approximately 80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunocytochemistry GRK3 antibody in CEM-NKr Human Cell Line by Immunocytochemistry (ICC). View Larger

GRK3 in CEM-NKr Human Cell Line. GRK3 was detected in immersion fixed CEM-NKr human Natural Killer cell resistant T-lymphoblastoid cell line using Mouse Anti-Human GRK3 Monoclonal Antibody (Catalog # MAB47851) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

GRK3 in Human Prostate Cancer Tissue. GRK3 was detected in immersion fixed paraffin-embedded sections of human prostate cancer tissue using Mouse Anti-Human GRK3 Monoclonal Antibody (Catalog # MAB47851) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in epithelial cells.

Background: GRK3

G protein-coupled receptor kinases (GRKs) are important modulators of G protein-coupled receptor (GPCR) signaling. Receptor phosphorylation by specific GRKs plays a key role in triggering rapid desensitization. The GRK family consists of 7 isoforms that share a central catalytic domain with homology to other serine/threonine kinases. The catalytic domain is flanked by an amino-terminal RGS domain of 183‑188 amino acids and a carboxyl-terminus of variable length. GRK3 (also known as beta -adrenergic receptor kinase 2, or beta ARK2) and GRK2 ( beta ARK1) are members of the beta -adrenergic receptor kinase subfamily. GRK3 may phosphorylate alpha -synuclein at S129, suggesting a potential involvement for this kinase in Parkinson’s disease.
