The TAF1B antibody targets TATA-box binding protein-associated factor 1B (TAF1B), a critical subunit of the RNA polymerase I (Pol I) transcription initiation complex. TAF1B, part of the SL1/Selectivity Factor 1 complex, plays a pivotal role in ribosomal RNA (rRNA) synthesis by recruiting Pol I to ribosomal DNA (rDNA) promoters. This process is essential for ribosome biogenesis, a fundamental cellular activity linked to cell growth, proliferation, and homeostasis. Dysregulation of TAF1B has been implicated in diseases marked by aberrant protein synthesis, such as cancers and developmental disorders.
TAF1B antibodies are widely used in research to investigate Pol I-mediated transcription mechanisms, nucleolar biology, and ribosome biogenesis. They enable detection and localization of TAF1B via techniques like Western blotting, immunofluorescence, and chromatin immunoprecipitation (ChIP). In cancer studies, these antibodies help assess TAF1B overexpression, which correlates with uncontrolled cell proliferation in tumors like neuroblastoma or glioblastoma. Additionally, they aid in exploring TAF1B's role in cellular stress responses and its interaction with oncogenic signaling pathways.
Available as polyclonal or monoclonal variants, TAF1B antibodies are typically validated in knockout models to ensure specificity. Their applications extend to diagnostics and drug development, particularly in targeting Pol I transcription as a therapeutic strategy. Researchers prioritize antibodies with high affinity and minimal cross-reactivity to avoid off-target effects in complex experimental systems.
