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) | ||||
abs | ATP-dependent RNA helicase abstrakt; ATP-dependent RNA helicase. Is essential for the directed and fasciculated early outgrowth of the bolwig nerves, as well as for its navigation at later stages. Is required during post-transcriptional gene expression. Plays a role during morphogenetic process, apoptosis and the establishment of cell polarity. (619 aa) |
