CSNK1G2. also known as casein kinase 1 gamma 2 (CK1γ2), is a serine/threonine protein kinase belonging to the CK1 family. It plays a regulatory role in multiple cellular processes, including Wnt/β-catenin signaling, cell cycle progression, and circadian rhythms. As a member of the CK1γ subfamily, CSNK1G2 shares structural homology with other isoforms (CK1γ1 and CK1γ3) but exhibits distinct tissue-specific expression patterns and substrate preferences. The kinase is characterized by a conserved catalytic domain and unique C-terminal regions that influence its subcellular localization and interaction partners.
Recombinant CSNK1G2 protein is typically produced in heterologous expression systems (e.g., E. coli or mammalian cells) to study its enzymatic activity and biological functions. Researchers utilize purified recombinant protein for in vitro kinase assays, structural studies, and drug discovery efforts targeting CK1 family members. Its role in phosphorylating key components of the Wnt pathway, particularly Dishevelled (DVL) proteins, has made it a focus in cancer research, as dysregulated Wnt signaling is implicated in various malignancies.
CSNK1G2's involvement in neurodegenerative diseases has also gained attention, with studies suggesting connections to tau phosphorylation in Alzheimer's pathology. The recombinant protein enables investigation of kinase-substrate relationships and screening for selective inhibitors. Structural analyses reveal autophosphorylation sites and regulatory mechanisms that modulate its activity. Mutational studies using recombinant variants help map functional domains critical for substrate recognition and membrane association through palmitoylation.
Commercial production of recombinant CSNK1G2 typically involves affinity tag purification (e.g., GST or His-tag) followed by activity validation using specific peptide substrates. Its biochemical properties, including ATP-binding affinity and sensitivity to kinase inhibitors, are routinely characterized to establish assay conditions for high-throughput screening platforms.
