Predicted to enable cyclin-dependent protein serine/threonine kinase regulator activity. Predicted to be involved in mitotic cell cycle phase transition and regulation of cyclin-dependent protein serine/threonine kinase activity. Predicted to be located in microtubule cytoskeleton. Predicted to be part of cyclin A1-CDK2 complex and cyclin A2-CDK2 complex. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in prostate cancer. Orthologous to human CCNA1 (cyclin A1). [provided by Alliance of Genome Resources, Apr 2022]
