Predicted to enable Lys48-specific deubiquitinase activity; Lys63-specific deubiquitinase activity; and thiol-dependent deubiquitinase. Acts upstream of or within several processes, including alpha-beta T cell differentiation; negative regulation of interleukin-17 production; and regulation of T-helper 17 type immune response. Orthologous to human OTUD5 (OTU deubiquitinase 5). [provided by Alliance of Genome Resources, Apr 2022]
