Predicted to enable thiol-dependent deubiquitinase and ubiquitin binding activity. Predicted to be involved in several processes, including cellular response to insulin stimulus; positive regulation of fat cell differentiation; and protein deubiquitination. Predicted to act upstream of or within adult walking behavior; eating behavior; and retina development in camera-type eye. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in cytoplasm. Orthologous to human UCHL3 (ubiquitin C-terminal hydrolase L3). [provided by Alliance of Genome Resources, Apr 2022]
