In eukaryotes a single class-1 translation termination factor eRF1 decodes the three stop codons: UAA, UAG and UGA. Some ciliates, like Euplotes, have a variant code, and here eRF1s exhibit UAR-only specificity, whereas UGA is reassigned as a sense codon. Since eukaryote eRF1 stop-codon recognition is associated with its N-terminal domain, structural(More)
Release factor eRF1 plays a key role in the termination of protein synthesis in eukaryotes. The eRF1 consists of three domains (N, M and C) that perform unique roles in termination. Previous studies of eRF1 point mutants and standard/variant code eRF1 chimeras unequivocally demonstrated a direct involvement of the highly conserved N-domain motifs (NIKS,(More)
Poly(A)-binding protein (PABP) is a major component of the messenger RNA-protein complex. PABP is able to bind the poly(A) tail of mRNA, as well as translation initiation factor 4G and eukaryotic release factor 3a (eRF3a). PABP has been found to stimulate translation initiation and to inhibit nonsense-mediated mRNA decay. Using a reconstituted mammalian in(More)
