Gene Regulation at the RNA Layer: RNA Binding Proteins in Intercellular Signaling Networks

Transcriptional regulators are sometimes believed to be the only targets through which signal transduction pathways regulate gene expression. Although it is certainly true that many well-characterized intercellular signaling pathways operate by modifying the activity of specific transcription factors, an increasing body of evidence indicates that external signals can modulate gene expression by posttranscriptional mechanisms.
