UniProtKB - O19175 (KC1A_PIG)
Protein
Casein kinase I isoform alpha
Gene
CSNK1A1
Organism
Sus scrofa (Pig)
Status
Functioni
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. May play a role in keratin cytoskeleton disassembly and thereby, it may regulate epithelial cell migration.By similarity
