Summary
Subcellular messenger RNA (mRNA) localization precisely controls protein synthesis. Once thought rare, mRNA targeting is now recognized as a prevalent mechanism with central roles in many cellular events in animal cells.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- Subcellular mRNA localization was historically considered a specialized mechanism.
- Recent findings indicate mRNA targeting is a widespread and fundamental cellular process.
- Evidence suggests crucial roles for mRNA localization in diverse cellular functions.
Purpose of the Study:
- To review the current understanding of mRNA localization mechanisms.
- To explore the functional significance of mRNA targeting in animal cells.
Main Methods:
- Literature review of recent studies on mRNA localization.
- Synthesis of current knowledge on mechanisms and functions.
Main Results:
- mRNA localization provides precise spatial control over protein production.
- This process is prevalent across a significant portion of the transcriptome.
- mRNA targeting is implicated in numerous essential cellular events.
Conclusions:
- mRNA localization is a fundamental aspect of cellular biology, not a niche mechanism.
- Understanding mRNA targeting mechanisms and functions is crucial for comprehending cellular processes.

02:22Regulated mRNA Transport
In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing specific...

01:34Nuclear Protein Sorting
Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...

01:46Nuclear Localization Signals and Import
Proteins targeted to the nucleus carry short stretches of amino acid sequences called the nuclear localization signal or NLS. Classical nuclear localization signals are of two types: monopartite and bipartite NLS. Monopartite classical NLS (cNLS) consists of a single cluster of 4-8 amino acids. Bipartite cNLS consists of two clusters of 2-3 amino acids and a 9-12 residue long proline-rich linker bridging the two clusters. Signal clusters are rich in positively charged amino acids such as...
01:37Eukaryotic Compartmentalization
One of the distinguishing features of eukaryotic cells is that they contain membrane-bound organelles, such as the nucleus and mitochondria, that carry out specialized functions. Since biological membranes are only selectively permeable to solutes, they help create a compartment with controlled conditions inside an organelle. These microenvironments are tailored to the organelle's specific functions and help isolate them from the surrounding cytosol.

02:53Ribosomal RNA Synthesis
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
