**Background of Recombinant Human TCF12 Protein**
Transcription factor 12 (TCF12), encoded by the *TCF12* gene, is a member of the basic helix-loop-helix (bHLH) E-protein family. It functions as a transcription regulator by binding to E-box DNA motifs (CANNTG) and plays critical roles in embryonic development, cell differentiation, and tissue-specific gene expression. TCF12 typically forms heterodimers with tissue-specific bHLH proteins, such as MYOD or NEUROD, to activate or repress target genes involved in neurogenesis, myogenesis, immune cell regulation, and craniofacial development.
Mutations in *TCF12* are linked to craniosynostosis syndromes, highlighting its importance in cranial suture homeostasis. Recombinant human TCF12 protein is engineered using expression systems (e.g., *E. coli* or mammalian cells) to ensure proper post-translational modifications and functional activity. It is widely used in *in vitro* studies to investigate molecular mechanisms of gene regulation, protein-DNA interactions, and cellular signaling pathways. Additionally, it serves as a tool for drug discovery targeting developmental disorders or cancers associated with TCF12 dysregulation. Purified TCF12 is often tagged (e.g., His, FLAG) for easier detection and purification in experimental workflows.
