HIV Tat-specific factor 1 is a protein that in humans is encoded by the HTATSF1 gene.[1][2]

Whereas most DNA sequence-specific transcription factors increase the rate of initiation and interact with enhancer or promoter DNA, human immunodeficiency virus-1 (HIV-1) Tat predominantly stimulates elongation and interacts with the trans-acting responsive (TAR) RNA element. Tat is essential for HIV replication.[supplied by OMIM][2]

Interactions[edit]

HTATSF1 has been shown to interact with SUPT5H[3] and GTF2F2.[3]
