Summary: Enables endopeptidase activator activity and endopeptidase inhibitor activity. Involved in regulation of G1/S transition of mitotic cell cycle and regulation of proteasomal protein catabolic process. Located in nucleus; polytene chromosome interband; and polytene chromosome puff. Part of catalytic step 2 spliceosome and precatalytic spliceosome. Colocalizes with cytoplasm. Is expressed in several structures, including Malpighian tubule primordium; adult heart; amnioserosa; embryonic/larval midgut primordium; and head epidermis primordium. Orthologous to human PSME3 (proteasome activator subunit 3). [provided by Alliance of Genome Resources, Dec 2024]
