HIV Tat-specific factor 1 is a protein that in humans is encoded by the HTATSF1 gene.^[5]^[6]

Function

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.^[6]

HTATSF1 has also been shown to be involved in intron retention, and is associated with splicing of mRNAs that encode ribosomal proteins.^[7] It is also associated with a naïve pluripotent state, although the relationship is complex and is strongly affected by other pluripotency factors such as Nanog and KLF2.^[7]

Interactions

HTATSF1 has been shown to interact with SUPT5H^[8] and GTF2F2.^[8]
