| + | The translation initiation factor eIF1A is necessary for directing the 43S preinitiation complex from the 5' end of the mRNA to the initiation codon in a process termed scanning. We have determined the solution structure of human eIF1A, which reveals an oligonucleotide-binding (OB) fold and an additional domain. NMR titration experiments showed that eIF1A binds single-stranded RNA oligonucleotides in a site-specific, but non-sequence-specific manner, hinting at an mRNA interaction rather than specific rRNA or tRNA binding. The RNA binding surface extends over a large area covering the canonical OB fold binding site as well as a groove leading to the second domain. Site-directed mutations at multiple positions along the RNA-binding surface were defective in the ability to properly assemble preinitiation complexes at the AUG codon in vitro. | ||
