An internal ribosome entry site, abbreviated IRES, is a nucleotide sequence that allows for translation initiation in the middle of a messenger RNA (mRNA) sequence as part of the greater process of protein synthesis. Usually, in eukaryotes, translation can be initiated only at the 5' end of the mRNA molecule, since 5' cap recognition is required for the assembly of the initiation complex.

Famous quotes containing the words internal, entry and/or site:
“Even if fathers are more benignly helpful, and even if they spend time with us teaching us what they know, rarely do they tell us what they feel. They stand apart emotionally: strong perhaps, maybe caring in a nonverbal, implicit way; but their internal world remains mysterious, unseen, “What are they really like?” we ask ourselves. “What do they feel about us, about the world, about themselves?””
—Augustus Y. Napier (20th century)
“When women can support themselves, have entry to all the trades and professions, with a house of their own over their heads and a bank account, they will own their bodies and be dictators in the social realm.”
—Elizabeth Cady Stanton (1815–1902)
“That is a pathetic inquiry among travelers and geographers after the site of ancient Troy. It is not near where they think it is. When a thing is decayed and gone, how indistinct must be the place it occupied!”
—Henry David Thoreau (1817–1862)
