Ires-transacting factors
WebThe majority of mRNAs in eukaryotic cells are translated via a method that is dependent upon the recognition of, and binding to, the methylguanosine cap at the 5' end of the mRNA, by a set of protein factors termed eIFs (eukaryotic initiation factors). WebJul 1, 2015 · Both, viral and eukaryotic IRES-dependent translation is enabled and regulated by so-called IRES trans-acting factors (ITAFs) [18–20]. These RNA-binding proteins were proposed either to act as RNA chaperones reshaping the RNA structure or to affect the recruitment of essential initiation factors including the 40S ribosomal subunit [5].

WebJul 1, 2015 · ITRES-transacting factors (ITAFs) are proteins that regulate IRES-translation. • Expression of ITAFs is frequently misregulated in cancer. • ITAFs control expression of proteins involved in key aspects of carcinogenesis. • Targeting ITAFs represent novel therapeutic approaches to fight cancer. Abstract
WebJan 15, 2011 · These so-called IRES trans-acting factors (ITAFs) (reviewed in refs. 11 and 16) are cellular RNA-binding proteins that have a variety of cellular functions in addition to promoting internal initiation; however, they do not appear to be involved in cap-dependent translation initiation.
