The process of lipid storage in insect oocytes: The involvement of β-chain of ATP synthase in lipophorin-mediated lipid transfer in the chagas’ disease vector Panstrongylus megistus (Hemiptera: Reduviidae)
β-ATPase was immunodetected in the microsomal fraction of the ovarian tissue. Lipophorin and β-ATPase partially co-localized in the membrane of the oocytes. β-ATPase blocking impaired the transfer of fatty acids from lipophorin to the oocytes. β-ATPase blocking did not affect lipophorin internalization in the oocytes. β-ATPase plays a role as a docking lipophorin receptor at the ovary.
