In the present study the abundance and potential modifications of another regulator of translation, namely the poly(A)-binding protein was analysed. This protein was shown to bind to mRNAs poly-(A)tails and link them to the sap-binding complex eIF4F. By this mechanism, cap dependent translation should by synergetically stimulated. In the present study, we have analysed the abundance of poly (A) binding protein in the course of meiotic maturation and we have elucidated potential expression of isoforms or post translational modifications of this protein by 2D-gelelectrophoresis.
