The MYC transcription factor network member MGA is a subunit of a non-canonical Polycomb complex, which, when inactivated, accelerates tumorigenesis in mouse models of cancer and proliferation in colon organoids.
Polycomb repressive complex 1.1 restricts precocious myeloid differentiation of hematopoietic stem/progenitor cells and expansion of myeloid progenitors, thereby serving as a gatekeeper of emergency myelopoiesis and myeloid transformation.
During heart maturation, embryonic ectoderm development as a chromatin remodeler triggers transcriptional silencing, while H3K27me3 is a passenger that is not sufficient for gene silencing.

Imprinted gene expression is set up during a critical window of early embryonic development, by the translation of parental imprints by oocyte-supplied Smchd1 into allele-specific gene silencing.

PCGF6 links sequence specific target recognition by the MAX/MGA transcription factor complex to PRC1 (polycomb repressive complex 1) -dependent transcriptional silencing of germ cell-specific genes in mouse pluripotent stem cells.

Growth-delayed offspring generated from eggs that lacked normal epigenetic programming exhibited a remarkable capacity to undergo late gestational fetal growth recovery, despite inefficient placental function.

Characterization of Drosophila female germ cell differentiation shows that nurse cells initiate Polycomb silencing by regulating Pcl and Scm levels to alter the biochemical properties of the PRC2 H3K27 methylase.
The E3 ubiquitin ligase activity of polycomb repressive complex 1 is stimulated by RYBP to support a histone modification-dependent communication between polycomb repressive complexes in mice.

Zebrafish early embryos initially package their developmental genes and enhancers in 'active' chromatin that subsequently receives polycomb repressive complex 1 (PRC1)-mediated histone H2A ubiquitylation, which confers silencing/poising – prior to Aebp2-PRC2-guided H3K27me3 addition.
