The HTATSF1 (N-term) antibody is a targeted reagent used to detect the N-terminal region of Human Tat-specific factor 1 (HTATSF1), a protein encoded by the HTATSF1 gene. HTATSF1. also known as CCNT1-interacting protein or HIV-1 Tat-specific factor 1. plays a critical role in transcriptional regulation, particularly in the elongation phase of RNA polymerase II (RNAP II)-mediated transcription. It interacts with cyclin-dependent kinase 9 (CDK9) and cyclin T1 (CCNT1), key components of the positive transcription elongation factor b (P-TEFb) complex, which facilitates the release of paused RNAP II at promoter-proximal regions. This activity is essential for the transcription of many cellular genes and is hijacked by the HIV-1 Tat protein to enhance viral replication.
The N-terminal region of HTATSF1 contains functional domains critical for its interaction with P-TEFb and other transcriptional regulators. Antibodies targeting this region are widely used in molecular biology to study HTATSF1’s expression, localization, and interactions in various cellular contexts. They are applied in techniques like Western blotting, immunoprecipitation (IP), and immunofluorescence (IF) to investigate transcriptional mechanisms, HIV-host interactions, and potential dysregulation in diseases such as cancer or viral infections. The HTATSF1 (N-term) antibody is particularly valuable for distinguishing full-length HTATSF1 from truncated isoforms or degradation products, aiding in functional studies of its role in gene expression and cellular homeostasis.
