Antibody Code: PK537

Antibody Target Type: Phosphosite-specific

Antibody Phosphosite: Y356

Protein UniProt: P25098

Protein SigNET: P25098

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human BARK1 (GRK2, ADRBK1) sequence peptide Cat. No.: PE-04ACJ85

Antibody Immunogen Sequence: THG(pY)MAP(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues T353 to P359; In the protein kinase catalytic domain activation T loop region between subdomains VII and VIII.

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: BARK1 (GRK2, ADRBK1) is a protein-serine/threonine kinase of the AGC group and GRK family. It is activated by G-beta/gamma subunit complex. Phosphorylation of S29 increases phosphotransferase activity. Phosphorylation of S670 inhibits G-beta/gamma-mediated activation of GRK2. Phosphorylation of Y13, Y86, Y92 and S685 increases interaction with G-alpha(q) and may induce protein degradation.
