There is a general enrichment of A's both upstream and downstream from the start codon with the obvious exception of the Shine-Dalgarno region and a decline in A as the last base before the start.
Thus when activated by DNA-binding proteins, the enhancer-promoter interaction is the control switch that initiates transcription by signaling the RNA polymerase to bind to the promoter and start codon ATG.
Given that AUG sequences occur randomly throughout a given mRNA, could one of these sequences act as a start codon if positioned at or near the 5' terminus of a message, and how commonly are AUG sequences found in such a position?

I discovered that the repeat region is translated in all three reading frames into aggregating dipeptide-repeat (DPR) proteins despite its intronic localization and lack of an ATG start codon.
The presence of a U insertion downstream to the second possible start codon for ORF2 (AUG2) in DcHEV strain 178C resembled the presence of a U insertion in HEV4 and wild boar HEV, leading to 3 possible start codons for its ORF2 but 1 possible start codon for its ORF3; whereas, the lack of this U insertion downstream to AUG2 in DcHEV strain 180C resembled the lack of U insertions in HEV1, HEV2 and HEV3, leading to only 1 possible start codon for its ORF2 but 3 possible start codons for its ORF3.
Initiation occurs when the ribosome binds the start codon in mRNA (AUG) with the amino acid methionine.
