Recombinant Human Casein kinase I gamma-2/CSNK1G2 (N-6His)

Source: E. coli. MW :47.6kD. Recombinant Human CSNK1G2 is produced by our E.coli expression system and the target gene encoding Met18-Lys415 is expressed with a 6His tag at the N-terminus. CSNK1G2 is a cytoplasmic protein which contains one protein kinase domain. It is amember of the CK1 Ser/Thr protein kinase family of the large casein kinase I (CKI) subfamily. CSNK1G2 participates in Wnt signaling, involves in brain development and vesicular trafficking and neurotransmitter releasing from small synaptic vesicles. It regulates fast synaptic transmission mediated by glutamate. SMAD3 phosphorylation promotes its ligand-dependent ubiquitination and subsequent proteasome degradation, thus inhibiting SMAD3-mediated TGF-beta responses. Protein function: Serine/threonine-protein kinase. Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. It can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates COL4A3BP/CERT, MTA1 and SMAD3. Involved in brain development and vesicular trafficking and neurotransmitter releasing from small synaptic vesicles. Regulates fast synaptic transmission mediated by glutamate. SMAD3 phosphorylation promotes its ligand-dependent ubiquitination and subsequent proteasome degradation, thus inhibiting SMAD3-mediated TGF-beta responses. Hyperphosphorylation of the serine-repeat motif of COL4A3BP/CERT leads to its inactivation by dissociation from the Golgi complex, thus down-regulating ER-to-Golgi transport of ceramide and sphingomyelin synthesis. Triggers PER1 proteasomal degradation probably through phosphorylation. [The UniProt Consortium]
