Once member of the family of eIF4E eukaryotic translation initiation factors is expressed only in oocytes in Tetrapoda. Suppressing the expression of this protein, eIF4E1B, by injecting Morpholinos into Xenopus tropicalis oocytes accelerated the maturation of oocytes after progesterone treatment, suggesting a repressor role for eIF4E1B during oocyte maturation.
