Protein
E3 ubiquitin-protein ligase RING1
Organism
Drosophila melanogaster
Length
435 amino acids
Function
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 complexes act via modification of histones, such as methylation, deacetylation, ubiquitination rendering chromatin heritably changed in its expressibility. May play a role in meiotic sister chromatid cohesion.
