Uba2 - ubiquitin-like modifier activating enzyme 2

Enables SUMO activating enzyme activity. Predicted to be involved in positive regulation of protein sumoylation and protein sumoylation. Predicted to be located in nucleoplasm. Predicted to be part of SUMO activating enzyme complex. Predicted to be active in cytoplasm. Is expressed in branchial arch; embryo; limb; and neural fold. Orthologous to human UBA2 (ubiquitin like modifier activating enzyme 2). [provided by Alliance of Genome Resources, Apr 2022]
