HTATSF1 Antibody (N-term)

Peptide Affinity Purified Rabbit Polyclonal Antibody (Pab)

  • WB - HTATSF1 Antibody (N-term) AP6654a
    Western blot analysis of HTATSF1 Antibody (N-term) (Cat. #AP6654a) in Jurkat cell line lysates (35ug/lane). HTATSF1 (arrow) was detected using the purified Pab.
  • IHC-P - HTATSF1 Antibody (N-term) AP6654a
    Formalin-fixed and paraffin-embedded human brain tissue with HTATSF1 Antibody (N-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

Protein Information
Function Functions as a general transcription factor playing a role in the process of transcriptional elongation. May mediate the reciprocal stimulatory effect of splicing on transcriptional elongation. In case of infection by HIV-1, it is up-regulated by the HIV-1 proteins NEF and gp120, acts as a cofactor required for the Tat-enhanced transcription of the virus.
Cellular Location Nucleus
Tissue Location Widely expressed.

HTATSF1 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.
