    ..We suggest that MEP-1 acts together with the MOG proteins to repress fem-3 mRNA and that it also functions in other pathways to control development more broadly. ..

    ..The dose-dependent control of proliferation and cell fate by FOG-1 has striking parallels with Xenopus CPEB, suggesting a conserved mechanism in animal development. ..
