Tcf4 | Transcription factor 4; Transcription factor that binds to the immunoglobulin enhancer Mu-E5/KE5-motif. Involved in the initiation of neuronal differentiation. Activates transcription by binding to the E box (5'- CANNTG-3'). Isoform 2 inhibits MYOD1 activation of the cardiac alpha- actin promoter. Binds to the E-box present in the somatostatin receptor 2 initiator element (SSTR2-INR) to activate transcription. May have a regulatory function in developmental processes as well as during neuronal plasticity. (670 aa) | ||||
Sox30 | Transcription factor SOX-30; Acts as both a transcriptional activator and repressor. Binds to the DNA sequence 5'-ACAAT- 3' and shows a preference for guanine residues surrounding this core motif. Binds to its own promoter and activates its own transcription. Required to activate the expression of postmeiotic genes involved in spermiogenesis. Binds to the promoter region of CTNNB1 and represses its transcription which leads to inhibition of Wnt signaling. Also inhibits Wnt signaling by binding to the CTNNB1 protein, preventing interaction of CTNNB1 with TCF7L2/TCF4 (By similarity). (782 aa) |
