Predicted to enable protein kinase binding activity. Predicted to be involved in axoneme assembly. Predicted to act 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. Predicted to be located in cytoskeleton; nucleus; and sperm flagellum. Predicted to be active in axonemal central apparatus. Orthologous to human SPAG16 (sperm associated antigen 16).
