Genome Regulation by Polycomb and Trithorax Proteins
نویسندگان
چکیده
Polycomb group (PcG) and trithorax group (trxG) proteins are critical regulators of numerous developmental genes. To silence or activate gene expression, respectively, PcG and trxG proteins bind to specific regions of DNA and direct the posttranslational modification of histones. Recent work suggests that PcG proteins regulate the nuclear organization of their target genes and that PcG-mediated gene silencing involves noncoding RNAs and the RNAi machinery.

Functional reconstruction of trans regulation of the Ultrabithorax promoter by the products of two antagonistic genes, trithorax and Polycomb.
Maintenance of the "on-off" state of Drosophila homeotic genes in Antennapedia and bithorax complexes requires activities of the trithorax and Polycomb groups of genes. To identify cis-acting sequences for functional reconstruction of regulation by both trithorax and Polycomb, we examined the expression patterns of several Ubx-lacZ transgenes that carry upstream fragments corresponding to a reg...
متن کاملThe Trithorax-mimic allele of Enhancer of zeste renders active domains of target genes accessible to polycomb-group-dependent silencing in Drosophila melanogaster.
Two antagonistic groups of genes, the trithorax- and the Polycomb-group, are proposed to maintain the appropriate active or inactive state of homeotic genes set up earlier by transiently expressed segmentation genes. Although some details about the mechanism of maintenance are available, it is still unclear how the initially active or inactive chromatin domains are recognized by either the trit...
متن کاملGRHL3/GET1 and Trithorax Group Members Collaborate to Activate the Epidermal Progenitor Differentiation Program
The antagonistic actions of Polycomb and Trithorax are responsible for proper cell fate determination in mammalian tissues. In the epidermis, a self-renewing epithelium, previous work has shown that release from Polycomb repression only partially explains differentiation gene activation. We now show that Trithorax is also a key regulator of epidermal differentiation, not only through activation...
متن کاملThe trithorax protein partner menin acts in tandem with EZH2 to suppress C/EBPα and differentiation in MLL-AF9 leukemia.
Trithorax and polycomb group proteins antagonistically regulate the transcription of many genes, and cancer can result from the disruption of this regulation. Deregulation of trithorax function occurs through chromosomal translocations involving the trithorax gene MLL, leading to the expression of MLL fusion proteins and acute leukemia. It is poorly understood how MLL fusion proteins block diff...
متن کاملFLC: a hidden polycomb response element shows up in silence.
A sizeable fraction of eukaryotic genomes is regulated by Polycomb group (PcG) and trithorax group (trxG) proteins, which play key roles in epigenetic repression and activation, respectively. In Drosophila melanogaster, homeotic genes are well-documented PcG targets; they are known to contain cis-acting elements termed Polycomb response elements (PREs), which bind PcG proteins and satisfy three...
