What pLDDT means and how to read it

Function

Component of the integrator complex, a multiprotein complex that terminates RNA polymerase II (Pol II) transcription in the promoter-proximal region of genes (PubMed:33243860, PubMed:38570683). The integrator complex provides a quality checkpoint during transcription elongation by driving premature transcription termination of transcripts that are unfavorably configured for transcriptional elongation: the complex terminates transcription by (1) catalyzing dephosphorylation of the C-terminal domain (CTD) of Pol II subunit POLR2A/RPB1 and SUPT5H/SPT5, (2) degrading the exiting nascent RNA transcript via endonuclease activity and (3) promoting the release of Pol II from bound DNA…

Subunit structure

Component of the Integrator complex, composed of core subunits INTS1, INTS2, INTS3, INTS4, INTS5, INTS6, INTS7, INTS8, INTS9/RC74, INTS10, INTS11/CPSF3L, INTS12, INTS13, INTS14 and INTS15 (PubMed:16239144, PubMed:33243860, PubMed:34762484, PubMed:38570683, PubMed:39032490). The core complex associates with protein phosphatase 2A subunits PPP2CA and PPP2R1A, to form the Integrator-PP2A (INTAC)…
