FUNCTION: Component of the positive transcription elongation factor b (P-TEFb) which consists of cdk9 and pch1, and which phosphorylates the C-terminal domain (CTD) of RNA polymerase II and spt5. CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. CATALYTIC ACTIVITY: ATP + [DNA-directed RNA polymerase] = ADP + [DNA-directed RNA polymerase] phosphate. ENZYME REGULATION: May be activated by autophosphorylation or phosphorylation by a separate activating kinase. SUBUNIT: Interacts with pch1 cyclin via its N-terminal domain. Via its C-terminal domain, interacts with RNA triphosphatase pct1 which is involved in mRNA capping. Interacts also with pcm1. SUBCELLULAR LOCATION: Nucleus. SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily. SIMILARITY: Contains 1 protein kinase domain. SEQUENCE CAUTION: Sequence=BAA21391.2; Type=Erroneous initiation; COPYRIGHT: Protein annotation is derived from the UniProt Consortium (http://www.uniprot.org/).
