Summary
We developed STRIPE-seq, a fast and affordable method for mapping transcription start sites (TSSs) using capped RNA sequencing. This technique simplifies TSS profiling and gene expression analysis in various cell types.
Area of Science:
- Molecular Biology
- Genomics
- Transcriptomics
Background:
- Accurate mapping of transcription start sites (TSSs) is crucial for understanding gene regulation.
- Existing genome-wide TSS profiling methods are often time-consuming and costly.
Purpose of the Study:
- To introduce STRIPE-seq, a novel, simple, rapid, and cost-effective protocol for high-throughput sequencing of capped RNA 5' ends.
- To enable efficient TSS profiling from minimal RNA input.
Main Methods:
- STRIPE-seq (Survey of TRanscription Initiation at Promoter Elements with high-throughput sequencing) protocol development.
- Depletion of uncapped RNA and library construction within approximately 5 hours.
- Application in yeast and human cell lines.
Main Results:
- STRIPE-seq successfully profiles genome-wide TSSs.
- The protocol requires as little as 50 ng of total RNA.
- STRIPE-seq also enables transcript quantification and differential gene expression analysis.
Conclusions:
- STRIPE-seq offers a straightforward and efficient method for probing transcriptional initiation landscapes.
- The protocol is cost-effective and rapid, making TSS profiling more accessible.
- Integrated computational workflows facilitate data analysis.

4.0K
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.

Initiation is the first step of transcription in eukaryotes. Prokaryotic RNA Polymerase (RNAP) can bind to the template DNA and start transcribing. On the other hand, transcription in eukaryotes requires additional proteins, called transcription factors, to first bind to the promoter region in the DNA template. This binding helps recruit the specific RNAP that can assemble on the DNA and start transcription.

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.
