C-myc internal ribosome entry site (IRES)
Encyclopedia
The c-myc internal ribosome entry site (IRES) is an RNA element
present in the 5' UTR
of the mRNA of C-myc and allows cap-independent translation. The mammalian c-myc gene is a proto-oncogene which is required for cell proliferation, transformation and death. c-myc mRNA has an alternative method of translation via internal ribosome entry where ribosomes are recruited to the IRES located in the 5' UTR thus bypassing the typical eukaryotic cap-dependent translation pathway.
Cis-regulatory element
A cis-regulatory element or cis-element is a region of DNA or RNA that regulates the expression of genes located on that same molecule of DNA . This term is constructed from the Latin word cis, which means "on the same side as". These cis-regulatory elements are often binding sites for one or...
present in the 5' UTR
Five prime untranslated region
A messenger ribonucleic acid molecule codes for a protein through translation. The mRNA also contains regions that are not translated: in eukaryotes these include the 5' untranslated region, 3' untranslated region, 5' cap and poly-A tail....
