In a eukaryotic cell, each messenger RNA ( mRNA ) is bound to a variety of proteins to form an mRNA –protein complex ( mRNP ). Together, these proteins impact nearly every step in the life cycle of an mRNA and are critical for the proper control of gene expression. In the cytoplasm, for instance, mRNPs affect mRNA translatability and stability and provide regulation of specific transcripts as well as global, transcriptome‐wide control. mRNPs are complex, diverse, and dynamic, and so they have been a challenge to understand. But the advent of high‐throughput sequencing technology has heralded a new era in the study of mRNPs . Here, I will discuss general principles of cytoplasmic mRNP organization and regulation. Using microRNA ‐mediated repression as a case study, I will focus on common themes in mRNPs and highlight the interplay between mRNP composition and posttranscriptional regulation. mRNPs are an important control point in regulating gene expression, and while the study of these fascinating complexes presents remaining challenges, recent advances provide a critical lens for deciphering gene regulation.
