Descripción

General description

Glycogen synthase kinase-3 (GSK-3), a multifunctional serine/threonine kinase, is a key regulator of numerous signaling pathways. Two isoforms of GSK-3 are reported in mammals: a 51 kDa GSK-3a and a 47 kDa GSK-3b. These two isoforms exhibit about 98% homology in their kinase domains, but share only about 36% identity in the last 76 C-terminal amino acid residues. GSK-3a contains a glycine-rich extension at its N-terminus. A minor (~15% of total) splice variant of GSK-3b, GSK-3b2, has also been identified, which contains a 13-residue insert within the kinase domain. It exhibits reduced kinase activity towards tau protein compared with ‘unspliced’ GSK-3b. GSK-3b2 is localized primarily to neuronal cell bodies, unlike unspliced GSK-3b that is also found in neuronal processes. GSK-3b plays a key inhibitory role in the Wnt signaling pathway. Wnt genes encode a large family of secreted, cysteine-rich proteins that are important in development and in maintenance of adult tissues. Abnormalities in Wnt signaling are reported to promote both human dgenerative diseases and cancer.

Specificity

Because of the extremely high conservation of this immunogen among the known enzymes of many different species, this antibody is predicted to cross-react with nearly all species homologues.

GSK3, α and β isoforms

Immunogen

18 residue synthetic peptide (C-KQLLHGEP NVSYICSRY) corresponding to amino acids 203-219 derived from a region of the catalytic domain (between subdomain VII and VIII) of the Drosophila GSK3/shaggy enzyme, coupled to ovalbumin. Clone 4G-1E.

Application

Anti-GSK3 Antibody, clone 4G-1E detects level of GSK3 & has been published & validated for use in IC & WB.
