GeneCards Summary for CSNK1G2 Gene
CSNK1G2 (Casein Kinase 1, Gamma 2) is a Protein Coding gene. Among its related pathways are GPCR Pathway and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include protein serine/threonine kinase activity and glycoprotein binding. An important paralog of this gene is CSNK1A1.
UniProtKB/Swiss-Prot for CSNK1G2 Gene
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.
Casein kinase I (CK1) is a monomeric serine-threonine protein kinase with 7 isoforms: alpha, beta, gamma1, gamma2, gamma3, delta and epsilon. CK1 is involved in a number of cellular processes including DNA repair, cell division, nuclear localization and membrane transport. CK1 isoforms also have key roles in the developmentally important Wnt and Hedgehog (Hh) signaling pathways. When Wnt is not bound to its receptor, CK1alpha is thought to phosphorylate beta-catenin as part of its degradation process. Upon binding of Wnt to its receptor (Frizzled) CK1epsilon phosphorylates the intracellular signaling protein, Dishevelled and CK1gamma directly phosphorylates the LRP5/6 co-receptor. These actions of CK1 facilitate signal transduction to the transcription factor, TCF, which mediates transcription of Wnt regulated genes. Similarly, CK1alpha plays a role in regulating Hh signaling by phosphorylating the signaling effector Ci-155 in the Hh unbound state, and then when Hh binds to Patched, CK1alpha phosphorylates the 7-TM co-receptor, Smoothened.
