Predicted to enable ubiquitin conjugating enzyme activity; ubiquitin protein ligase binding activity; and ubiquitin-ubiquitin ligase activity. Acts upstream of or within intrinsic apoptotic signaling pathway in response to endoplasmic reticulum stress. Predicted to be located in cytoplasm and filopodium tip. Predicted to be active in nucleus. Orthologous to human UBE2K (ubiquitin conjugating enzyme E2 K). [provided by Alliance of Genome Resources, Apr 2022]
