Enables ubiquitin conjugating enzyme binding activity. Contributes to ubiquitin conjugating enzyme activity. Acts upstream of or within error-free postreplication DNA repair. Predicted to be located in cytoplasm and nucleoplasm. Predicted to be part of UBC13-UEV1A complex and ubiquitin ligase complex. Predicted to be active in nucleus. Orthologous to several human genes including PEDS1-UBE2V1 (PEDS1-UBE2V1 readthrough). [provided by Alliance of Genome Resources, Apr 2022]
