TFcheckpoint

TFcheckpoint compiles a curated, evidence-based database of sequence-specific DNA-binding RNA polymerase II transcription factors (DbTFs) to support gene regulatory network assembly and analysis.

Key Features:

• Comprehensive compilation: Aggregates data from nine distinct resources to produce a comprehensive list of putative mammalian transcription factors focused on DbTFs.
• Evidence-based annotations: Annotates each transcription factor with experimental evidence and supporting literature that confirm its sequence-specific DNA-binding RNA polymerase II TF function.
• Standardized evidence justification: Provides standardized justifications for functional classifications to address inconsistencies in supporting evidence across sources.
• Focused exclusion criteria: Systematically excludes general TFs, mediator complexes, and chromatin modifiers to maintain emphasis on true sequence-specific DbTFs.
• High-quality knowledge source: Curates detailed, literature-supported annotations intended for genome-scale regulatory network studies.

Scientific Applications:

• Gene regulatory network studies: Supports construction and analysis of gene regulatory networks with verified DbTF functional roles.
• Functional genomics: Facilitates interpretation of TF roles within genomic regulatory contexts using experimentally supported annotations.
• Systems biology: Provides a reliable compendium of DbTFs for systems-level models that require precise regulatory component information.

Methodology:

Collecting potential transcription factors from multiple reputable sources; conducting literature review to identify and confirm experimental references supporting sequence-specific DNA-binding function; excluding non-DbTFs such as general TFs, mediator complexes, and chromatin modifiers; annotating each transcription factor with detailed evidence from experimental studies and relevant literature.
