JIL-1 | Chromosomal serine/threonine-protein kinase JIL-1; Phosphorylates 'Ser-10' of histone H3. May regulate gene expression by establishing or maintaining the structure of more open chromatin regions. Also required for normal polytene chromosome structure, for oogenesis and for viability throughout development. Regulates the structure of polytene chromosomes in salivary glands. May phosphorylate 'Ser-1' of histone H2A. (1207 aa) | ||||
Sce | E3 ubiquitin-protein ligase RING1; E3 ubiquitin-protein ligase that mediates monoubiquitination of 'Lys-118' of histone H2A, thereby playing a central role in histone code and gene regulation. H2A 'Lys-118' ubiquitination gives a specific tag for epigenetic transcriptional repression. Polycomb group (PcG) protein. 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. PcG [...] (435 aa) |
