Tcf7 | Transcription factor 7; Transcriptional activator involved in T-cell lymphocyte differentiation. Necessary for the survival of CD4(+) CD8(+) immature thymocytes. Isoforms lacking the N-terminal CTNNB1 binding domain cannot fulfill this role. Binds to the T-lymphocyte-specific enhancer element (5'-WWCAAAG-3') found in the promoter of the CD3E gene. May also act as feedback transcriptional repressor of CTNNB1 and TCF7L2 target genes. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7 and CTNNB1 (By similarity); Belongs to the TCF/LEF family. (303 aa) | ||||
Ovol2 | Transcription factor Ovo-like 2; Zinc-finger transcription repressor factor. Plays a critical role in maintaining the identity of epithelial lineages by suppressing epithelial-to mesenchymal transition (EMT) mainly through the repression of ZEB1, an EMT inducer. Positively regulates neuronal differentiation. Suppresses cell cycling and terminal differentiation of keratinocytes by directly repressing MYC and NOTCH1 (By similarity). Important for the correct development of primordial germ cells in embryos. Belongs to the krueppel C2H2-type zinc-finger protein family. (274 aa) |
