Abstract Canonical Polycomb repressive complex 1 (cPRC1) preserves cell fate decisions by repressing aberrant transcription of developmental regulator genes. We report the cryo-electron microscopy structure of the human cPRC1 holocomplex assembled from RING1B, BMI1, PHC2 and CBX7 bound to an H3K27me3-modified mononucleosome together with the ubiquitin-conjugating enzyme UBCH5C.
