A component of the GATOR subcomplex GATOR2 which functions as an activator of the amino acid-sensing branch of the TORC1 signaling pathway. The two GATOR subcomplexes, GATOR1 and GATOR2, regulate the TORC1 pathway in order to mediate metabolic homeostasis, female gametogenesis and the response to amino acid limitation and complete starvation. GATOR2 activates the TORC1 signaling pathway through the inhibition of the GATOR1 subcomplex, controlling the switch to cell proliferation and growth under nutrient replete conditions and during female oocyte development. Component of the GATOR complex consisting of mio, Nup44A/Seh1, Im11, Nplr3, Nplr2, Wdr24, Wdr59 and Sec13. Within the GATOR complex, probable component of the GATOR2 subcomplex which is likely composed of mio, Nup44A/Seh1, Wdr24, Wdr59 and Sec13.
