abstract：:An interaction between human poly(A)-binding protein (PABP) et human eRF3 has been demonstrated using a double-hybrid approach and in vitro assays. Here, we show that the binding of both proteins is conserved through evolution. We also demonstrate that the last 39 C-terminal amino acids of PABP contain the interface t...
