BAP1 structure model.
Left Panel: Cartoon depiction of the BAP1 UCH domain (purple) noting p.Leu14
(red sphere) involved in organizing a flexible crossover loop and other flexible portions of the domain
(salmon) that order upon ubiquitin substrate (cyan) binding. Uch37-like domain (ULD) is shown in green.
Right Upper Panel: Zoom-in of wild type BAP1 leucine 14 residue with atom radii depicted in dots
interacting with surrounding residues (side chains within 4 Å displayed in stick). Right Lower Panel:
Zoom-in of BAP1 histidine 14 mutant with atom radii (dots) revealing clashes with surrounding residues.
