Model confidence (pLDDT)

The mean pLDDT of this model is 77.5 (confident overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

pLDDT band	Meaning	Share of residues
Above 90	Very high: backbone and side chains are usually accurate	16%
70 to 90	Confident: backbone generally right	59%
50 to 70	Low: treat with caution	17%
Below 50	Very low: often disordered regions	9%

What pLDDT means and how to read it

Function

The 26S proteasome is involved in the ATP-dependent degradation of ubiquitinated proteins. The regulatory (or ATPase) complex confers ATP dependency and substrate specificity to the 26S complex (By similarity)

Subunit structure

Interacts with UBR1 and CIC1
