WebIGR-IRES (intragenic regions-internal ribosome entry sites) can assemble 80S ribosomes from 40S and 60S ribosomal subunits in the absence of eIF2, Met-tRNAi, or GTP hydrolysis and without a coding triplet in the ribosomal P-site. Authors also showed IGR-IRES can direct translation of a protein whose N-terminal residue is not methionine.
