Popis

General description

80 kDa

The beta-adrenergic receptor kinase specifically phosphorylates the agonist-occupied form of the beta-adrenergic and related G protein-coupled receptors. Overall, the ADRBK2 enzyme, also known as GRK3, has 85% amino acid similarity with ADRBK1, with the protein kinase catalytic domain having 95% similarity. The ADRBK2 mRNA is approximately 8 kilobases with a distribution similar to that of ADRBK1. These data suggest the existence of a family of receptor kinases which may serve broadly to regulate receptor function.
GRK2 phosphorylates the beta2 adrenergic receptor. It is a ubiquitous cytosolic enzyme that specifically phosphorylates the activated form of the beta-adrenergic and related G-protein-coupled receptors.

Immunogen

Epitope: a.a. 483-485

Partial GST fusion protein corresponding to the GRK3 (βARK2) carboxyl terminus (a.a. 467-688). This immunogen shares homology with GRK2 (βARK1). The minimal epitope recognized by the antibody is a.a. 483-485. Clone C5/1.1.

Application

Detect GRK 2/3 (βARK 1/2) using this Anti-GRK 2/3 (βARK 1/2) Antibody, clone C5/1.1 validated for use in IP & WB.

Immunoprecipitation:
A previous lot of this antibody was used to immunoprecipitate GRK2/3 from transfected cells, as shown by an independent laboratory.

Biochem/physiol Actions

This antibody recognizes GRK2/3, Mr 80 kDa. Additional bands at 85 and 50 kDa are also detected when using higher concentrations of the antibody.

Physical form

Format: Purified

Protein G Purified

Purified mouse monoclonal IgG2aκ in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl containing 0.05% sodium azide. Frozen solution.

Preparation Note

Stable for 1 year at -20°C from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Analysis Note

Control
Positive Antigen Control: Catalog #12-305, 3T3/A31 lysate. Add 2.5 μL of 2-mercapto-ethanol/100 μL of lysate and boil for 5 minutes to reduce the preparation. Load 20 μg of reduced lysate per lane for minigels.

Routinely evaluated by immunoblot on RIPA lysates from mouse 3T3/A31 fibroblasts, bovine brain cytosol preparation, rat L6 myoblasts, human A431 carcinoma or human HeLa cell lysates.

Western Blot Analysis:
0.1-1 µg/mL of this lot detected GRK2/3 (βARK 1/2) in RIPA lysates from mouse 3T3/A31 fibroblasts. Previous lots of this antibody detected GRK2/3 in bovine brain cytosol preparation, rat L6 myoblasts, human A431 carcinoma and human HeLa cell RIPA lysates.
