Please look at the allele reports for the complete phenotype data

Drosophila initiation factor eIF-4F is composed of two subunits, one is encoded by eIF-4E and the other by eIF-4G, a 200kD protein. eIF-4G is required for the translation of endogenous mRNAs in cell-free systems made from Drosophila embryos, and can cross-link uncapped, but not m⁷G capped RNA. eIF-4E cross-links with m⁷G capped RNA.

(Zapata et al., 1994)

RNAi screen using dsRNA made from templates generated with primers directed against this gene results in aberrantly short, monopolar spindles when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.
