HTATSF1
The protein encoded by this gene functions as a cofactor for the stimulation of transcriptional elongation by HIV-1 Tat, which binds to the HIV-1 promoter through Tat-TAR interaction. This protein may also serve as a dual-function factor to couple transcription and splicing and to facilitate their reciprocal activation. Alternatively spliced transcript variants have been found for this gene.

Interaction
Component of a complex which is at least composed of HTATSF1/Tat-SF1, the P-TEFb complex components CDK9 and CCNT1, RNA polymerase II, SUPT5H, and NCL/nucleolin. Interacts with GTF2F2/RAP30 and POLR2A. Interacts with TCERG1/CA150. Interacts with SF3A2/SAP62 and the spliceosomal U small nuclear ribonucleoproteins (snRNPs).
