Predicted to enable endopeptidase inhibitor activity; proteasome binding activity; and thiol-dependent deubiquitinase. Involved in forebrain morphogenesis; lateral ventricle development; and midbrain development. Predicted to be located in cytosol; nucleolus; and nucleoplasm. Predicted to be part of Ino80 complex. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; brain ventricular layer; genitourinary system; nose; and orbito-sphenoid. Orthologous to human UCHL5 (ubiquitin C-terminal hydrolase L5). [provided by Alliance of Genome Resources, Apr 2022]
