Protein Structure
|
|
Function |
Regulatory subunit of cyclin-dependent kinases that mediates activation of target kinases. Plays a role in transcriptional regulation via its role in regulating the phosphorylation of the C-terminal domain (CTD) of the large subunit of RNA polymerase II (POLR2A). {ECO:0000269PubMed:10574912, ECO:0000269PubMed:22012619, ECO:0000269PubMed:9632813}.
