Involved in proteasome-mediated ubiquitin-dependent protein catabolic process. Part of proteasome core complex. Is expressed in several structures, including adult head; adult heart; embryonic/larval midgut primordium; germline cell; and mesoderm. Orthologous to human PSMB3 (proteasome 20S subunit beta 3).
