What pLDDT means and how to read it

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 (PubMed:21282530). 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. Possibly contributes to the target selectivity of the PRC1 complex by binding specific regions of chromatin (PubMed:18927235). Recruitment to chromatin might occur in an H3K27me3-independent fashion (By similarity). May have a PRC1-independent function in embryonic stem cells (By…

Subunit structure

Component of a PRC1-like complex (PubMed:21282530). Distinct PRC1-like core complexes are composed of a RING1 subunit (RING1B or RING1A), one of the six PCGF proteins (PCGF1-6), one PHC protein (PHC1-3) and one of the CBX proteins (CBX2, CBX4, CBX6, CBX7 or CBX8) (PubMed:21282530). Interacts with PCGF1, PCGF2, PCGF3, BMI1, PCGF5, PCGF6, RING1 and RNF2 (PubMed:18927235, PubMed:21282530). May…
