Enables protein kinase activity. Involved in protein phosphorylation. Acts upstream of or within cell morphogenesis. Located in ciliary basal body. Part of ribonucleoprotein complex. Is expressed in several structures, including central nervous system; endocrine gland; metanephros; retina nuclear layer; and thymus primordium. Orthologous to several human genes including CSNK1A1 (casein kinase 1 alpha 1). [provided by Alliance of Genome Resources, Apr 2022]
