What pLDDT means and how to read it

Function

Protein that possesses intrinsic ATP-dependent nucleosome-remodeling activity and is both required for DNA repair and heterochromatin organization (PubMed:22960744, PubMed:21820097). Combines the ATP-dependent ability to exchange histones, with the chaperone-like ATP-independent activity to deposit histones and assemble nucleosomes (PubMed:21820097). Promotes DNA end resection of double-strand breaks (DSBs) following DNA damage: probably acts by weakening histone DNA interactions in nucleosomes flanking DSBs (PubMed:22960744). Required for the restoration of heterochromatin organization after replication (PubMed:21549307). Acts at replication sites to facilitate the maintenance of…

Subunit structure

Binds to DNA preferentially in the vicinity of transcriptional start sites. Interacts with MSH2 and TRIM28. Part of a complex composed of TRIM28, HDAC1, HDAC2 and EHMT2. Interacts with PCNA
