Control of MYEOV protein synthesis by upstream open reading frames.

The myeov gene has been isolated by the tumorigenicity assay and is localized at chromosome 11q13, a frequent site for chromosomal rearrangements in various carcinomas and B-cell neoplasms. In addition, myeov is coamplified with cyclin D1 and overexpressed in carcinomas of various organs. The mechanisms of myeov regulation remain enigmatic. The 5'-untranslated region (5'-UTR) of the myeov gene ...

Translational Control via Protein-Regulated Upstream Open Reading Frames

Analysis of the regulation of msl-2 mRNA by Sex lethal (SXL), which is critical for dosage compensation in Drosophila, has uncovered a mode of translational control based on common 5' untranslated region elements, upstream open reading frames (uORFs), and interaction sites for RNA-binding proteins. We show that SXL binding downstream of a short uORF imposes a strong negative effect on major rea...

Control of eukaryotic protein synthesis by upstream open reading frames in the 5'-untranslated region of an mRNA.

Control of gene expression is achieved at various levels. Translational control becomes crucial in the absence of transcription, such as occurs in early developmental stages. One of the initiating events in translation is that the 40 S subunit of the ribosome binds the mRNA at the 5'-cap structure and scans the 5'-untranslated region (5'-UTR) for AUG initiation codons. AUG codons upstream of th...

Dual modes of natural selection on upstream open reading frames.

Upstream open reading frames (uORFs) are common features of eukaryotic genes, occurring in 10%-25% of 5' leader sequences. Upstream ORFs that have been subjected to experimental analysis have been generally found to decrease translational efficiency of the downstream coding sequence. Previous investigations of uORFs in mammals and yeast have detected uORFs conserved over long evolutionary dista...
