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) | ||||
Mei4 | Meiosis-specific protein MEI4; Required for DNA double-strand breaks (DSBs) formation in unsynapsed regions during meiotic recombination. Probably acts by forming a complex with IHO1/CCDC36 and REC114, which activates DSBs formation in unsynapsed regions, an essential step to ensure completion of synapsis ; Belongs to the MEI4L family.
