CCNT1

CCNT1 (Cyclin T1) is a Protein Coding gene. Diseases associated with CCNT1 include Human Immunodeficiency Virus Type 1. Among its related pathways are Formation of HIV elongation complex in the absence of HIV Tat and Gene Expression. Gene Ontology (GO) annotations related to this gene include chromatin binding and transcription regulatory region DNA binding. An important paralog of this gene is CCNT2.

Cyclin T1

Regulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin-T1) complex, also called positive transcription elongation factor B (P-TEFb), which is proposed to facilitate the transition from abortive to productive elongation by phosphorylating the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNA Pol II).
(Microbial infection) In case of HIV or SIV infections, binds to the transactivation domain of the viral nuclear transcriptional activator, Tat, thereby increasing Tat's affinity for the transactivating response RNA element (TAR RNA). Serves as an essential cofactor for Tat, by promoting RNA Pol II activation, allowing transcription of viral genes.
