Identification of the 5′ UTR-binding proteins.

<p>(A) Silver staining of sequential RNA column purified proteins is shown. The bands specific for the X/P UTR probe (X/P) are indicated. M/G represents a control RNA column using the 5′ UTR of M/G mRNA. (B) The specificity of identified proteins was determined by Western blotting using antibodies specific to each protein (see <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1000654#s4" target="_blank">Materials and Methods</a>).</p>
