What pLDDT means and how to read it

Function

Component of the COP9 signalosome (CSN) complex that acts as an regulator of the ubiquitin (Ubl) conjugation pathway by mediating the deneddylation of the cullin subunit of SCF-type E3 ubiquitin-protein ligase complexes. The CSN complex is involved in the regulation of the mating pheromone response. CSN12 forms a complex with THP3 that is recruited to transcribed genes and required for transcription elongation

Subunit structure

Component of a COP9 signalosome-like (CSN) complex, composed of RRI1/CSN5, CSN9, RRI2/CSN10, PCI8/CSN11, CSN12 and CSI1. In the complex, it probably interacts directly with RRI1/CSN5, CSN9, RRI2/CSN10 and CSI1. Interacts with SEM1 and THP3
