CSNK1A1/Casein Kinase I alpha Protein, Human (Active, sf9, GST)
Casein kinase I α is a member of casein kinases that exhibits a preference for phosphorylation of acidic proteins such as casein. It phosphorylates many substrates, including CTNNB1 at "Ser-45" involved in Wnt signaling. CSNK1A1/Casein Kinase I alpha Protein, Human (sf9, GST) is the recombinant human-derived Casein Kinase I alpha protein, expressed by Sf9 insect cells , with N-GST labeled tag.

Description
Casein kinase I α is a member of casein kinases that exhibits a preference for phosphorylation of acidic proteins such as casein. It phosphorylates many substrates, including CTNNB1 at "Ser-45" involved in Wnt signaling. CSNK1A1/Casein Kinase I alpha Protein, Human (sf9, GST) is the recombinant human-derived Casein Kinase I alpha protein, expressed by Sf9 insect cells , with N-GST labeled tag.
Background
Casein Kinase I alpha, a member of the casein kinase family, is characterized by its preference for acidic substrates such as caseins. Demonstrating versatility, it phosphorylates a diverse array of proteins and actively participates in Wnt signaling by phosphorylating CTNNB1 at 'Ser-45.' Additionally, Casein Kinase I alpha may contribute to the phosphorylation of PER1 and PER2, suggesting a potential role in circadian rhythm regulation. Beyond its involvement in cellular signaling pathways, this kinase may play a crucial role in chromosome segregation during mitosis and regulate epithelial cell migration by influencing keratin cytoskeleton disassembly. Furthermore, Casein Kinase I alpha acts as a positive regulator of mTORC1 and mTORC2 signaling in response to nutrient stimuli, mediating the phosphorylation of the DEPTOR inhibitor. In another context, it functions as an inhibitor of NLRP3 inflammasome assembly through the phosphorylation of NLRP3, highlighting its diverse roles in cellular processes.
