Summary
We developed iTiSS, an accurate transcription start site (TSS) caller for eukaryotes. This integrative approach reduces false positives by analyzing multiple datasets, improving genomic analysis.
Area of Science:
- Genomics
- Molecular Biology
- Bioinformatics
Background:
- Experimental identification of transcription start sites (TSS) is crucial for understanding gene regulation.
- Existing methods for genome-wide TSS identification are prone to experiment-specific biases, leading to false positives.
Purpose of the Study:
- To develop an accurate and generic transcription start site (TSS) caller for eukaryotic genomes.
- To reduce false-positive calls in TSS identification by integrating complementary datasets.
Main Methods:
- Developed iTiSS, an integrative approach for TSS calling.
- Utilized joint analysis of several complementary datasets to improve accuracy.
- Implemented iTiSS in Java (v1.8), ensuring platform independence.
Main Results:
- iTiSS demonstrates high accuracy in identifying transcription start sites.
- The integrative approach substantially reduces the number of false-positive TSS calls.
- iTiSS is applicable to various TSS profiling experiments in eukaryotes.
Conclusions:
- iTiSS offers a robust solution for accurate and reliable TSS identification.
- The tool minimizes experimental biases, enhancing the quality of genomic data analysis.
- iTiSS is freely available for academic and non-commercial use.

General Transcription Factors
6.2K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Transcription Initiation
18.2K
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.

Non-LTR Retrotransposons
12.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

In-situ Hybridization
10.0K
In situ hybridization (ISH) is a technique used to detect and localize specific DNA or RNA molecules in cells, tissue, or tissue sections using a labeled probe. The technique was first used in 1969 for the investigation of nucleic acids. It is currently an essential tool in scientific research and clinical settings, especially for diagnostic purposes.
Types of probes and labels
A probe is a complementary strand of DNA or RNA that binds to corresponding nucleotide sequences in a cell. Many...

Eukaryotic Transcription Activators
11.9K
Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

Inheritance of Chromatin Structures
6.9K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...
