What pLDDT means and how to read it

Function

Involved in pre-mRNA splicing as component of the spliceosome (PubMed:11991638, PubMed:28076346, PubMed:28502770). As a component of the minor spliceosome, involved in the splicing of U12-type introns in pre-mRNAs (Probable). Required for the specific splicing of CDKN1A pre-mRNA; the function probably involves the recruitment of U2AF2 to the mRNA. May recruit PPIL1 to the spliceosome. May be involved in cyclin-D1/CCND1 mRNA stability through the SNARP complex which associates with both the 3'end of the CCND1 gene and its mRNA. Involved in transcriptional regulation. Modulates TGF-beta-mediated transcription via association with SMAD proteins, MYOD1-mediated transcription via association…

Subunit structure

Identified in the spliceosome C complex (PubMed:11991638, PubMed:28076346, PubMed:28502770). Associates with U4/U6-U5 tri-small nuclear ribonucleoproteins (U4/U6-U5 tri-snRNPs). Component of the minor spliceosome, which splices U12-type introns (PubMed:33509932). Interacts with SKI, SMAD2,SMAD3, RBPJ, RB1, PABPN1, MAGEA1, SIRT1, FOXN3, U2AF2, DAXX and ATP1B4. Interacts with PPIL1…
