Ctcfl | Transcriptional repressor CTCFL; Testis-specific DNA binding protein responsible for insulator function, nuclear architecture and transcriptional control, which probably acts by recruiting epigenetic chromatin modifiers. Plays a key role in gene imprinting in male germline, by participating in the establishment of differential methylation at the IGF2/H19 imprinted control region (ICR). Directly binds the unmethylated H19 ICR and recruits the PRMT7 methyltransferase, leading to methylate histone H4 'Arg-3' to form H4R3sme2. This probably leads to recruit de novo DNA methyltransferases a [...] (636 aa) | ||||
Cdc25c | M-phase inducer phosphatase 3; Functions as a dosage-dependent inducer in mitotic control. Tyrosine protein phosphatase required for progression of the cell cycle. Directly dephosphorylates CDK1 and activates its kinase activity. When phosphorylated, highly effective in activating G2 cells into prophase (By similarity). May be involved in regulating the proliferation of T-lymphocytes following cytokine stimulation. (447 aa) |
