Product Type Specific: Protein kinase pan-specific antibody

Antibody Code: NK070

Antibody Target Type: Pan-specific

Protein UniProt: P49841

Protein SigNET: P49841

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human GSK3b sequence peptide Cat. No.: PE-01AQU90

Antibody Immunogen Sequence: CAHSFFDELRDPNVK

Antibody Immunogen Description: Corresponds to amino acid residues C335 to K349; Kinase catalytic subdomain 11

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.

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

Scientific Background: GSK3b is a protein-serine/threonine kinase of the CMGC group and GSK family. It is a critical enzyme in glycogen metabolism, and plays a role in pathological conditions such as cancer, diabetes, and neurological diseases. This kinase is highly expressed and widely distributed in most tested human tissues. Orthologues of GSK3b are amongst the most highly conserved protein kinases in animals, plants, fungi and unicellular eukaryotes. GSK3b is activated by phosphorylation at Y216 by MEK1 and MEK2, and inhibited by phosphorylation of S9. GSK3b phosphorylates and inhibits glycogen synthase. It is implicated in the regulation of several physiological processes, including control of glycogen and protein synthesis by insulin, and modulation of the transcription factors AP-1 and CREB. Transient transfection of human GSK3b into Chinese hamster ovary cells stably transfected with individual human tau isoforms leads to hyperphosphorylation of tau. GSK3b has been linked with the development of Alzheimer’s disease, bipolar disorder, and Type 2 diabetes. Mutations leading to upregulation of GSK3b are also implicated in ovarian, prostate, pancreatic, colorectal, neuroblastoma, and glioblastoma neoplasms, by positively regulating cyclin D1 and thus promoting cell cycle progression.
