Predicted to enable ubiquitin binding activity; ubiquitin protein ligase binding activity; and ubiquitin-like protein-specific protease activity. Predicted to be involved in cellular response to DNA damage stimulus; negative regulation of nitrogen compound metabolic process; and protein K48-linked deubiquitination. Predicted to act upstream of or within protein deubiquitination. Predicted to be located in cytoplasm. Predicted to be active in nucleus. Is expressed in several structures, including endocrine gland; genitourinary system; nervous system; oral epithelium; and sensory organ. Orthologous to human OTUB1 (OTU deubiquitinase, ubiquitin aldehyde binding 1). [provided by Alliance of Genome Resources, Apr 2022]
