GeneCards Summary for CSNK1A1 Gene

CSNK1A1 (Casein Kinase 1, Alpha 1) is a Protein Coding gene. Diseases associated with CSNK1A1 include lung cancer. Among its related pathways are Signaling by GPCR and GPCR Pathway. GO annotations related to this gene include protein serine/threonine kinase activity and protein kinase activity. An important paralog of this gene is CSNK1G2.

UniProtKB/Swiss-Prot for CSNK1A1 Gene

  • 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 CTNNB1 at Ser-45. May phosphorylate PER1 and PER2. May play a role in segregating chromosomes during mitosis.

Tocris Summary for CSNK1A1 Gene

  • 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.
