Cdk12 - cyclin-dependent kinase 12

Enables protein kinase binding activity. Acts upstream of or within negative regulation of stem cell differentiation. Predicted to be located in nuclear speck. Predicted to be part of cyclin K-CDK12 complex and cyclin/CDK positive transcription elongation factor complex. Predicted to be active in nucleus. Is expressed in several structures, including blastocyst; early embryo; future brain; primitive streak; and unsegmented mesenchyme. Orthologous to human CDK12 (cyclin dependent kinase 12).
