| + | [https://www.uniprot.org/uniprot/IF6_YEAST IF6_YEAST] Binds to the 60S ribosomal subunit and prevents its association with the 40S ribosomal subunit to form the 80S initiation complex in the cytoplasm. Is also involved in ribosome biogenesis. Associates with pre-60S subunits in the nucleus and is involved in its nuclear export. Cytoplasmic release of TIF6 from 60S subunits and nuclear relocalization is promoted by the GTPase RIA1/EFL1 and by SDO1. Also required for pre-rRNA processing.<ref>PMID:10085284</ref> <ref>PMID:11779510</ref> <ref>PMID:11238882</ref> <ref>PMID:17353896</ref> <ref>PMID:18256024</ref> <ref>PMID:11101899</ref> | ||

| + | Ribosome anti-association factor eIF6 (originally named according to translation initiation terminology as eukaryotic initiation factor 6) binds to the large ribosomal subunit, thereby preventing inappropriate interactions with the small subunit during initiation of protein synthesis. We have determined the X-ray structures of two IF6 homologs, Methanococcus jannaschii archaeal aIF6 and Sacchromyces cerevisiae eIF6, revealing a phylogenetically conserved 25 kDa protein consisting of five quasi identical alpha/beta subdomains arrayed about a five-fold axis of pseudosymmetry. Yeast eIF6 prevents ribosomal subunit association. Comparative protein structure modeling with other known archaeal and eukaryotic homologs demonstrated the presence of two conserved surface regions, one or both of which may bind the large ribosomal subunit. | ||
