Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Regulated mRNA Transport

Regulated 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...

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Ribosomal RNA Synthesis

Ribosomal 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,...

Background:

RNA localization to specific subcellular sites is a widespread cellular mechanism.
This process spatially regulates protein production, impacting development and cellular physiology.
Mechanistic details exist for some RNAs, but a broad understanding of RNA localization systems is lacking.

Purpose of the Study:

To review the current understanding of RNA localization.
To identify which RNAs are localized, the sequences involved, and the protein factors.
To discuss the biological implications and assess genome-wide studies of RNA localization.

Main Methods:

Review of prominent systems and techniques for studying individual RNA messages.
Analysis of recent genome-wide studies on RNA localization.
Discussion of adapting high-throughput approaches for RNA localization research.

Main Results:

RNA localization is a fundamental process with significant roles in cellular function.
Identifying specific RNAs, sequences, and protein factors involved in localization is an active area of research.
Genome-wide studies are beginning to reveal the scope and complexity of RNA localization.

Conclusions:

Assessing the generality and specificity of RNA localization systems remains challenging.
High-throughput approaches hold promise for advancing the study of RNA localization.
Further research is needed to fully understand the implications of RNA localization across the transcriptome.
