**Background of Recombinant Human TAF7 Protein**
TAF7 (TATA-box binding protein-associated factor 7) is a subunit of the transcription factor IID (TFIID) complex, a critical component of the RNA polymerase II-mediated transcription initiation machinery. It plays a pivotal role in regulating gene expression by bridging interactions between TFIID, other transcriptional activators, and co-regulators. TAF7 contains a conserved histone-fold domain (HFD) that facilitates dimerization with other TAFs, contributing to the structural integrity of TFIID. Additionally, it modulates the acetyltransferase activity of TAF1. influencing promoter recognition and transcription initiation.
Recombinant human TAF7 protein is typically produced using *E. coli* or mammalian expression systems, enabling studies of its biochemical properties and interactions. Its recombinant form is essential for *in vitro* assays, including chromatin-binding studies, transcriptional reconstitution experiments, and structural analyses. Dysregulation of TAF7 has been implicated in diseases such as cancer and neurodegeneration, highlighting its potential as a therapeutic target. Research on recombinant TAF7 continues to shed light on its dual roles in transcription regulation and cellular homeostasis.
