Casein kinase 1α (CK1α) in the CK1 protein family plays a regulatory role in several important signalling pathways involved in membrane transport, the cell cycle, chromosome segregation, apoptosis, autophagy, cell metabolism, developmental differentiation, the circadian rhythm, the immune response, neurodegeneration, and cancer (Jiang et al., 2018). The gene discussed is CSNK1A1; the disease is cancer.
