Source-derived summary

In molecular biology, the Ure2 internal ribosome entry site (IRES) is an RNA element present in the 5' UTR of the mRNA of Ure2. It allows 5' cap- and eIF4E-independent translation of an N-terminally truncated form of Ure2. This truncated form lacks the prion-forming domain. It is a 104 nucleotide region, smaller than most viral IRES elements, which forms a stem-loop structure. EIF2A represses this IRES resulting in an inhibition of translation of the N-terminally truncated Ure2.

Editorial summary

“Ure2 internal ribosome entry site (IRES)” enters the record as open-knowledge reference entry. Crown Archives preserves that source wording while asking what Ure2, internal and ribosome can confirm, complicate or overturn.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—2009, 1261—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Ure2, internal and ribosome.
Editorial analysis

Why this record matters

“Ure2 internal ribosome entry site (IRES)” is worth following because a concise public description often conceals a longer documentary argument. Here, Ure2, internal and ribosome provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Oct 3, 2025. The linked authority identifier is Q17130580. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009 and 1261.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
