Predicted to enable several functions, including alpha-2A adrenergic receptor binding activity; cysteine-type peptidase activity; and ubiquitin protein ligase binding activity. Involved in sensory perception of pain and ubiquitin-dependent protein catabolic process. Predicted to be located in several cellular components, including neuron projection terminus; neuronal cell body; and nucleoplasm. Predicted to be active in cytoplasm. Predicted to colocalize with plasma membrane. Biomarker of retinal disease. Human ortholog(s) of this gene implicated in Alzheimer's disease; Parkinson's disease; and hereditary spastic paraplegia. Orthologous to human UCHL1 (ubiquitin C-terminal hydrolase L1). [provided by Alliance of Genome Resources, Apr 2022]
