Complex of CDK11A and Cyclin D3 proteins. Recombinant human CDK11A (Cyclin-dependent kinase 11A), encompassing amino acids 361-780 (end). Recombinant human Cyclin D3 (also known as CCND3), full length encompassing amino acids 1-292 (end). Both constructs contain an N-terminal GST-tag. The two proteins were co-expressed in a Baculovirus infected Sf9 cell expression system and affinity purified.
