CCNT1

A gene on chromosome 12q13.11 that encodes a member of the highly conserved cyclin family, which regulates CDK kinases. Cyclin T1 binds tightly to CDK9, forming a major subunit of the transcription elongation factor p-TEFb, which interacts with, and acts as a cofactor of, HIV-1’s Tat protein, and is required for full activation of viral transcription.

In addition, mouse studies have already resulted in some discoveries about HIV, including the identification of co-receptors, cyclin T1 (a necessary co-factor for Tat and TAR during transcriptional elongation), and host factors required for viral assembly and release.
