Transcriptome-wide profiling of Yeast Phosphofructokinase 1 and 2 RNA targets

ABSTRACT: The RNA targets of the yeast Pfk1 and Pfk2 were mapped on a transcriptome scale using formaldehyde-assisted crosslinking and RNA-protein immunoprecipitation followed by high throuput sequencing (fRIP-seq). Tandem affinity purification (TAP) tagged Pfk1 and Pfk2 were usesd to capture the transcritps bound by Pfk1 and Pfk2. We also included a mock IP control i.e. wild type treated exactly the same way as the fRIP-seq samples to account for non-specific RNA interactions with the beads. Moreover, we ran total RNA-seq on wild type control for data normalization. We found that Pfk1 and Pfk2 bind mainly to mRNAs that code for proteins invovled in distinct functions . Our data suggests that, besides their well-characterized functions as glycolytic enzymes, they perfom additional functions as RNA-binding involved in posttranscriptional regulation of gene expression.
