Predicted to enable protein homodimerization activity. Predicted to be involved in several processes, including intraciliary transport involved in cilium assembly; protein localization to centrosome; and regulation of centrosome duplication. Predicted to act upstream of or within cilium organization and spermatid development. Predicted to be located in several cellular components, including acrosomal vesicle; ciliary basal body; and sperm head-tail coupling apparatus. Predicted to be active in centriolar satellite. Predicted to colocalize with centrosome. Orthologous to human CEP131 (centrosomal protein 131). [provided by Alliance of Genome Resources, Apr 2022]
