Predicted to enable SUMO-specific isopeptidase activity; identical protein binding activity; and importin-alpha family protein binding activity. Predicted to be involved in protein desumoylation; protein export from nucleus; and regulation of proteasomal ubiquitin-dependent protein catabolic process. Predicted to be located in cytosol. Predicted to be part of protein-containing complex. Orthologous to human DESI1 (desumoylating isopeptidase 1). [provided by Alliance of Genome Resources, Apr 2022]
