        (Davies, 2001.3.15)

        Identification: Protein that interacts with vas protein in a yeast two-hybrid assay.

        (Johnstone et al., 1999)

        Mutations in eIF5B are recessive lethal. Ovaries derived from homozygous germ line clones contain fewer egg chambers than normal, and those egg chambers that do form often have too many nurse cells and two oocytes.
