What pLDDT means and how to read it

Function

Modulates chromatin structure and DNA damage response by regulating key determinants of chromatin compaction and DNA damage response (PubMed:19638409). Binds H3K4me3-containing chromatin and promotes DNA condensation by recruiting corepressors such as TRIM28 and H3K9 methyltransferase SETDB1 (PubMed:23034801). Required for normal chromosome condensation during the early stages of mitosis. Required for normal chromosome separation during mitosis (PubMed:19638409). Increases both chromatin-associated levels and activity of H3K9 methyltransferases, such as SETDB1, thus enhancing H3K9 trimethylation (PubMed:23034801). Essential for testicular stem-cell differentiation and sustained…

Subunit structure

Interacts with histone H3 that is trimethylated at 'Lys-4' (H3K4me3) (PubMed:23034801, Ref.10). Interacts with GSK3B (PubMed:19638409). Interacts with TRIM28 (PubMed:23034801). Interacts with SETDB1; the interaction probably enhances SETDB1 chromatin-associated levels and activity (PubMed:23034801)
