Model confidence (pLDDT)

The mean pLDDT of this model is 83.5 (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	44%
70 to 90	Confident: backbone generally right	43%
50 to 70	Low: treat with caution	8%
Below 50	Very low: often disordered regions	6%

What pLDDT means and how to read it

Function

Probable metalloprotease involved in proper assembly of pre-ribosomal particles during the biogenesis of the 60S ribosomal subunit. Accompanies the pre-60S particles to the cytoplasm

Subunit structure

Component of the nucleoplasmic and cytoplasmic pre-60S ribosomal particles. Interacts directly with REI1

Subcellular location

Cytoplasm, Nucleus
