Enables protein kinase activity. Acts upstream of or within negative regulation of non-motile cilium assembly and photoreceptor cell maintenance. Located in several cellular components, including axoneme; ciliary tip; and photoreceptor cell cilium. Is expressed in several structures, including brain; nasal cavity epithelium; neural retina; respiratory system; and testis. Human ortholog(s) of this gene implicated in retinitis pigmentosa 62. Orthologous to human MAK (male germ cell associated kinase). [provided by Alliance of Genome Resources, Apr 2022]
