GTF2F2 (general transcription factor IIF subunit 2) is a core component of TFIIF, a general transcription initiation factor essential for RNA polymerase II recruitment and transcription initiation 1. As part of the TFIIF complex, GTF2F2 facilitates polymerase II binding to the initiation complex and regulates transcription elongation 2. Beyond canonical transcription functions, GTF2F2 participates in T cell biology, where the related factor GTF2F1 promotes gene expression during T cell activation through mTORC1 signaling 3. GTF2F2 holds significant clinical relevance across multiple disease contexts. In ovarian cancer, GTF2F2 knockdown suppressed cell migration and invasion while altering epithelial-mesenchymal transition markers (increased E-cadherin, decreased N-cadherin), suggesting GTF2F2 promotes cancer progression 4. In lung cancer, GTF2F2 was identified as a hub gene independently regulated by miR-708-5p, where it participates in polymerase II-mediated transcription to accelerate tumor growth 5. GTF2F2 also emerged as a hub gene in polycystic ovary syndrome pathogenesis, contributing to preterm labor risk 6. In neuroblastoma, GTF2F2 was identified as an NRF-1-regulated gene positively mediating neurite outgrowth 7. Additionally, hypoxic regulation of GTF2F2 in glioma cells is modulated by IRE1 signaling 8, implicating GTF2F2 in stress-response transcription control.
