Normal role description: | Cyclin T1 can associate with CDK9 kinase, and is a major subunit of the transcription elongation factor p-TEFb, which, when complexed, can interact and act as a cofactor for HIV-1 Tat protein, thereby increasing Tat's affinity for the transactivating response RNA element. CCNT1 is necessary for full activation of viral transcription; the complex is involved in the phosphorylation and regulation of the C-terminal domain of the largest RNA polymerase II subunit, allowing transcription of viral genes. |
