What pLDDT means and how to read it

Function

Component of the small ribosomal subunit (PubMed:36517592). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:36517592). Has endonuclease activity and plays a role in repair of damaged DNA (PubMed:7775413). Cleaves phosphodiester bonds of DNAs containing altered bases with broad specificity and cleaves supercoiled DNA more efficiently than relaxed DNA (By similarity). Displays high binding affinity for 7,8-dihydro-8-oxoguanine (8-oxoG), a common DNA lesion caused by reactive oxygen species (ROS) (By similarity). Has also been shown to bind with similar affinity to intact and damaged DNA (By similarity). Stimulates the…

Subunit structure

Component of the 40S small ribosomal subunit (PubMed:36517592). Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs. Interacts with HNRPD. Interacts with PRMT1; the interaction methylates RPS3. Interacts with SUMO1; the interaction sumoylates RPS3. Interacts with UBC9. Interacts with CDK1; the interaction phosphorylates RPS3. Interacts with PRKCD; the interaction…
