What pLDDT means and how to read it

Function

Transcriptional repressor (PubMed:33433058). Together with PHD finger-containing proteins (e.g. PHD1, PAIPP2/PHD2, AIPP2/PHD3, PHD4, PHD5 and PHD6), cooperates to form a BAH-PHD bivalent histone reader complex able to read histone H3 lysine 27 trimethylation (H3K27me3) and low-methylated H3K4 histone marks in order to regulate transcription, especially to prevent early flowering; H3K27me3 reader of this complex (PubMed:33277495, PubMed:33433058). CPL2 is subsequently recruited to form a BAH-PHD-CPL2 complex (BPC) in order to silence several H3K27me3 and low-methylated H3K4 enriched loci, including AGO5, via the phosphorylation state-dependent inhibition of Pol II release from the…

Subunit structure

Interacts with MOM1 (PubMed:27113777). Component of the ASI1-AIPP1-EDM2 (AAE) RNA regulatory complex composed of at least AIPP1/EDM3, ASI1 and EDM2 and may contain CPL2, AIPP2 and AIPP3/BDT1 (PubMed:28808009). Part of the BAH-PHD bivalent histone reader complex that contains AIPP2, PAIPP2 and AIPP3/BDT1; the BAH-PHD module associates with CPL2 to form the BAH-PHD-CPL2 complex (BPC) for…
