Polycomb group genes (PcG) encode a group of about 16 proteins that were first identified
in Drosophila as repressors of homeotic genes. PcG proteins are present in all metazoans …

Polycomb group (PcG) proteins are responsible for maintaining the silenced transcriptional
state of many developmentally regulated genes. PcG proteins are organized into …

Polycomb group (PcG) proteins are conserved regulatory proteins that repress transcription
of particular target genes in animals and plants. Studies over the past decade have …

Polycomb response elements (PREs) are regulatory sites that mediate the silencing of
homeotic and other genes. The bxd PRE region from the Drosophila Ultrabithorax gene can …

Genes of the Polycomb group (PcG) of Drosophila encode proteins necessary for the
maintenance of transcriptional repression of homeotic genes. PcG proteins are thought to …

Polycomb-group response elements (PREs) are DNA elements through which the Polycomb-
group (PcG) of transcriptional repressors act. Many of the PcG proteins are associated with …

The Polycomb group (Pc-G) genes are essential for maintaining the proper spatially
restricted expression pattern of the homeotic loci during Drosophila development. The Pc-G …

Polycomb group (PcG) proteins are able to maintain the memory of silent transcriptional
states of homeotic genes throughout development. In Drosophila, they form multimeric …

Polycomb group (PcG) proteins repress homeotic genes in cells where these genes must
remain inactive during development. This repression requires cis-acting silencers, also …

ABSTRACT The Polycomblike gene of Drosophila melanogaster, a member of the Polycomb
Group of genes, is required for the correct spatial expression of the homeotic genes of the …
