What pLDDT means and how to read it

Function

Associates with chromatin regions downstream of transcriptional start sites of active genes and thus regulates gene transcription (PubMed:23629655, PubMed:23798402, PubMed:24130829). Chromatin interaction is mediated via the binding to tri-methylated histone H3 at 'Lys-4' (H3K4me3) (PubMed:23798402, PubMed:24130829). Key regulator of hematopoiesis involved in terminal myeloid differentiation and in the regulation of hematopoietic stem cell (HSCs) self-renewal by a mechanism that involves DNA methylation (By similarity). Also acts as an important cell cycle regulator, participating in cell cycle regulatory network machinery at multiple cell cycle stages including G1/S transition, S phase…

Subunit structure

Component of a complex composed of KMT2E (isoform 3), OGT and USP7; the complex stabilizes KMT2E, preventing KMT2E ubiquitination and proteasomal-mediated degradation (PubMed:26678539). Isoform 3 interacts (via N-terminus) with OGT (via TRP repeats) (PubMed:23629655, PubMed:26678539). Isoform 3 interacts with deubiquitinating enzyme USP7 (via MATH domain) (PubMed:26678539). Isoform 3 interacts…
