General annotation (Comments)

Function	Component of a Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility. In the PRC1 complex, it is required to stimulate the E3 ubiquitin-protein ligase activity of RNF2/RING2. Ref.11 Ref.14 Ref.17
Subunit structure	Component of a PRC1-like complex. Interacts with RING1 and RING2 By similarity. Interacts vwith CBX7 and CBX8. Interacts with SPOP. Part of a complex consisting of BMI1, CUL3 and SPOP. Interacts with E4F1. Ref.7 Ref.8 Ref.12 Ref.14 Ref.15 Ref.17
Subcellular location	Nucleus. Cytoplasm Ref.14 Ref.16.
Post-translational modification	Monoubiquitinated By similarity. May be polyubiquitinated; which does not lead to proteasomal degradation.
Miscellaneous	The hPRC-H complex purification reported by Ref.9 probably presents a mixture of different PRC1-like complexes.
Sequence similarities	Contains 1 RING-type zinc finger.
