Description TaT is a transcriptional transactivator protein that binds to a regulatory element in the HIV-1 long terminal repeat. By recruiting P-TEFb to TAR, TaT promotes transcription of viral mRNA. This arginine-rich TAT peptide penetrates plasma membrane directly, but not through endocytosis. TaT has similar immunosuppressive effects as transforming growth factor-beta (TGF beta) and both inhibit lymphocyte proliferation.
