Predicted to enable cyclin binding activity; protein kinase binding activity; and protein serine/threonine kinase activity. Predicted to be involved in RNA metabolic process; hemopoiesis; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within negative regulation of stem cell differentiation. Predicted to be located in Golgi apparatus; cytosol; and nuclear speck. Predicted to be part of cyclin K-CDK13 complex and cyclin/CDK positive transcription elongation factor complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in congenital heart defects, dysmorphic facial features, and intellectual developmental disorder. Orthologous to human CDK13 (cyclin dependent kinase 13).
