Biological Activity

Description

CCNK Protein, Human (sf9, GST) is the recombinant human-derived CCNK, expressed by Sf9 insect cells , with GST labeled tag.

Background

CDK13-CCNK is a regulatory subunit of cyclin-dependent kinases (CDKs) that mediates activation of target kinases. It plays a role in transcriptional regulation by regulating the phosphorylation of the C-terminal domain (CTD) of the large subunit of RNA polymerase II (POLR2A).
