Sae1 - SUMO1 activating enzyme subunit 1

Predicted to enable several functions, including ATP-dependent protein binding activity; SUMO activating enzyme activity; and protein C-terminus binding 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 genitourinary system. Orthologous to human SAE1 (SUMO1 activating enzyme subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
