label: histone H2B conserved C-terminal lysine deubiquitinase activity
label_lc: histone h2b conserved c-terminal lysine deubiquitinase activity
description: "A histone deubiquitinase that cleaves ubiquitin from the conserved C-terminal lysine residue of a histone H2B protein to which it is conjugated. The conserved lysine residue is K119 in fission yeast, K123 in budding yeast, and K120 in mammals."
