Abstract

The maturation, localization, stability, and translation of messenger RNAs (mRNAs) are regulated by a wide variety of mRNA-binding proteins. Identification of the complete set of mRNA-binding proteins is a key step in understanding the regulation of gene expression. Herein, we describe a method for identifying yeast mRNA-binding proteins in a systematic manner using UV crosslinking, purification of polyA(+) mRNAs under denaturing conditions, and mass spectrometry to identify covalently bound proteins.
