Here's a concise overview of recombinant human TAF1A protein:
TAF1A (TATA-box binding protein-associated factor 1A) is a critical component of the transcription factor IID (TFIID) complex, essential for RNA polymerase II-mediated gene transcription. This 55kDa protein contains conserved domains including a histone-fold motif that facilitates heterodimer formation with other TAFs. Its primary function involves bridging interactions between core promoter elements and regulatory proteins during transcriptional initiation. Recombinant TAF1A production typically employs bacterial (E. coli) or mammalian expression systems, enabling studies of its structural and functional properties. Researchers utilize purified TAF1A to investigate TFIID assembly mechanisms, promoter recognition specificity, and transcriptional dysregulation in diseases. Recent studies suggest TAF1A's involvement in cell cycle regulation and differentiation processes, with abnormal expression patterns observed in certain cancers. The recombinant protein serves as vital material for crystallography studies, protein interaction assays, and reconstituting minimal transcription systems. Challenges in production include maintaining proper folding of its secondary structure elements critical for DNA-binding activity. Current research focuses on its potential as a therapeutic target and biomarker for transcription-related disorders.
