Summary
Enables ubiquitin activating enzyme activity. Involved in several processes, including glucose homeostasis; larval midgut cell programmed cell death; and nervous system development. Located in dendrite. Is expressed in several structures, including embryonic/larval digestive system; embryonic/larval nervous system; extended germ band embryo; presumptive embryonic/larval system; and trunk ectoderm. Human ortholog(s) of this gene implicated in VEXAS syndrome and X-linked spinal muscular atrophy 2. Orthologous to several human genes including UBA1 (ubiquitin like modifier activating enzyme 1).
