Predicted to enable ATP binding activity and cyclin-dependent protein serine/threonine kinase activity. Acts upstream of or within blastocyst development; negative regulation of apoptotic signaling pathway; and regulation of mitotic nuclear division. Located in nucleus. Is expressed in several structures, including alimentary system; blastocyst; brain; early embryo; and integumental system. Orthologous to several human genes including CDK11B (cyclin dependent kinase 11B). [provided by Alliance of Genome Resources, Apr 2022]
