Sfmbt | Polycomb protein Sfmbt; Polycomb group (PcG) protein that binds to the Polycomb response elements (PREs) found in the regulatory regions of many genes. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility. Necessary but not sufficient to recruit a functional Pc [...] (1243 aa) | ||||
Wnt4 | Protein Wnt-4; Binds as a ligand to a family of frizzled seven-transmembrane receptors and acts through a cascade of genes on the nucleus. Acts downstream of homeotic complex genes in the visceral mesoderm and is required for embryonic segmentation. Also required for cell movement and FAK regulation during ovarian morphogenesis.
