Leaky scanning is a mechanism used during the initiation phase of eukaryotic translation that enables regulation of gene expression. During initiation, the small 40S ribosomal subunit (as a 43S PIC) "scans" or moves in a 5' → 3' direction along the 5'UTR to locate a start codon to commence elongation.
