Enables ubiquitin conjugating enzyme activity. Predicted to be involved in several processes, including cellular protein metabolic process; cellular response to interferon-beta; and negative regulation of cAMP-mediated signaling. Predicted to be located in cytosol and nuclear speck. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and immune system. Orthologous to human CDC34 (cell division cycle 34, ubiqiutin conjugating enzyme). [provided by Alliance of Genome Resources, Apr 2022]
