    Protocol

    Specificity / Sensitivity

    GRK2 Antibody recognizes endogenous levels of total GRK2 protein.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human GRK2 protein. Antibodies are purified by peptide affinity chromatography.

    Background

    G protein-coupled receptor kinase 2 (GRK2), also known as beta-adrenergic receptor kinase 1 (beta-ARK1), is a member of the GRK family, which phosphorylates the activated form of G protein-coupled receptors (GPCRs) and initiates the desensitization process of GPCR (1). GRK2 kinase activity and cellular localization are tightly regulated by interactions with activated receptors, G-beta and G-gamma subunits, adaptor proteins, phospholipids, caveolin, and calmodulin, as well as by phosphorylation (1). Protein kinase C (PKC) phosphorylation enhances GRK2 activity by promoting its membrane localization and by abolishing the inhibitory association of calmodulin (2,3). Protein kinase A (PKA) phosphorylates GRK2 at Ser685, facilitating the association of GRK2 with a beta-adrenergic receptor (4). Erk inhibits GRK2 activity via phosphorylation at Ser670 (5). Src phosphorylates GRK2 at multiple tyrosine residues (Tyr13, 86, and 92), which activates GRK2 activity and promotes GRK2 degradation (6,7).
