Enables protein kinase binding activity. Involved in cilium assembly. Acts upstream of or within several processes, including cell motility in response to calcium ion; epithelial cilium movement involved in extracellular fluid movement; and sperm axoneme assembly. Located in cytoskeleton; nucleus; and sperm flagellum. Orthologous to human SPAG16 (sperm associated antigen 16). [provided by Alliance of Genome Resources, Apr 2022]
