Pc | Polycomb group protein Pc; 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. Component of the PcG multiprotein PRC1 complex, a complex that acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-118', rendering chromatin heritably changed in its expressibility. Promotes locus-specif [...] (390 aa) | ||||
Lhr | Lethal hybrid rescue (Lhr) encodes a protein required to repress transposable element and satellite DNA expression. It also has a gain-of-function phenotype of causing lethality in F1 male hybrids between D. melanogaster and D. simulans. (334 aa) |
