CDK9 is the member of the cyclin-dependent kinase pair (CDK9/cyclin-T) complex, also called positive transcription elongation factor b (P-TEFb), which facilitates the transition from abortive to production elongation by phosphorylating the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAP II), SUPT5H and RDBP.
The CDK9/cyclin-K complex has also a kinase activity toward CTD of RNAP II and can substitute for P-TEFb in vitro.The protein encoded by this gene is a member of the cyclin-dependent protein kinase (CDK) family.
CDK family members are highly similar to the gene products of S.
cerevisiae cdc28, and S.
pombe cdc2, and known as important cell cycle regulators.
This kinase was found to be a component of the multiprotein complex TAK/P-TEFb, which is an elongation factor for RNA polymerase II-directed transcription and functions by phosphorylating the C-terminal domain of the largest subunit of RNA polymerase II.
This protein forms a complex with and is regulated by its regulatory subunit cyclin T or cyclin K.
HIV-1 Tat protein was found to interact with this protein and cyclin T, which suggested a possible involvement of this protein in AIDS.
