Plasma membrane acetic acid exporter, relieving the stress induced upon cells within hemocytes, and thus enabling increased proliferation and virulence against Galleria mellonella larvae. Confers resistance to weak acid and oxidative stress, but not to antifungal drugs (PubMed:29184852). Expression is up-regulated during internalization in hemocytes and in the presence of hydrogen peroxide stress, but surprisingly, down-regulated upon exposure to acetic acid (PubMed:29184852). Leads to intracellular accumulation of acetate and decreases the ability to kill Galleria mellonella larvae by decreasing proliferation in the host hemolymph after infection (PubMed:29184852). Belongs to the major facilitator superfamily. CAR1 family.
