Zinc Finger Homeobox Protein 1A (ZFHX1A)

TCF8 encodes a human zinc finger transcription factor that represses T-lymphocyte-specific IL2 gene expression by binding to a negative regulatory domain 100 nucleotides 5-prime of the IL2 transcription start site.

Delta-Ef1 selectively transactivated the promoters of the SMC differentiation marker genes Acta2 and Myh11, and it physically interacted with Srf and Smad3, resulting in synergistic activation of the Acta2 promoter. Chromatin immunoprecipitation assays and knockdown experiments showed that delta-Ef1 was involved in control of SMC differentiation programs induced by Tgf-beta (TGFB1) signaling. Overexpression of delta-Ef1 inhibited neointima formation and promoted SMC differentiation.
