Sec61β Deficiency Disrupts Drosophila Oogenesis Through UPR-Mediated Defects in Germ Cell Proliferation and Differentiation
It is found that knockdown of Sec61β in either germ cells or somatic cells of ovaries causes complete female sterility, with a small size of ovaries from larval to adult stages, significant reduction in germ cell numbers beginning in the late third-instar larval stage and a complete absence of germ cells in pupal and adult ovaries.
