Predicted to enable cyclin-dependent protein serine/threonine kinase regulator activity. Predicted to be involved in several processes, including mitotic cell cycle phase transition; multi-ciliated epithelial cell differentiation; and regulation of cyclin-dependent protein serine/threonine kinase activity. Predicted to act upstream of or within cell division and cell projection organization. Located in cytoplasm. Is expressed in brain and nasal epithelium. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 29. Orthologous to human CCNO (cyclin O). [provided by Alliance of Genome Resources, Apr 2022]
