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) | ||||
dimm | Protein dimmed; Transcription factor that regulates neurosecretory (NS) cell function and neuroendocrine cell fate. Acts as a master regulator of common NS functions such as Phm expression and neuropeptide production. Plays a role as a regulator of peptide-containing large dense-core vesicle (LDCV) production and peptidergic cell differentiation. Controls transcription of FMRFamide in Tv neuronal cells and Fur1 in Ap-let cells (Tvb and dorsal apterous cells). Also required for up- regulation of Phm in Tv and Ap-let cells, and expression of three neuropeptide genes, Ms, FMRFamide and Lk [...] (390 aa) |
