Antibody Immunogen Description: Corresponds to amino acid residues F511 to G521; In protein kinase catalytic domain activation T-loop 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: PKG1 (PRKG1) is a protein-serine/threonine kinase of the AGC group and PKG family. It is activated by cGMP, which is generated in response to nitric oxide. Phosphorylation at T59 increases phosphotransferase activity and its affinity for cGMP Phosphorylation at T517 increases phosphotransferase activity. An R177Q mutation in AAT8 results in a constitutively active form of PKG1, which also has reduced cGMP binding.
