Predicted to be involved in G2/M transition of mitotic cell cycle; positive regulation of cyclin-dependent protein serine/threonine kinase activity; and regulation of canonical Wnt signaling pathway. Predicted to be located in nucleus. Predicted to be part of cytoplasmic cyclin-dependent protein kinase holoenzyme complex. Predicted to be active in plasma membrane. Orthologous to human CCNY (cyclin Y). [provided by Alliance of Genome Resources, Apr 2022]
