About CDK9

Cytogenetic location: 9q34.11 Genomic coordinates (GRCh38): 9:127,786,034-127,790,792 (from NCBI)

This gene has 5 transcripts (splice variants), 208 orthologues and 26 paralogues. Ubiquitous expression in ovary (RPKM 32.0), spleen (RPKM 23.0) and 25 other tissues.

Summary

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. [provided by RefSeq, Jul 2008]
