Cis-regulatory Sequences02:02

Cis-regulatory Sequences

11.7K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

RNA Polymerase II Accessory Proteins

10.9K
Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

Global Regulatory Systems

659
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

RNA Editing02:23

RNA Editing

9.9K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

Area of Science:

  • Molecular Biology
  • Genomics
  • Bioinformatics

Background:

  • Argonaute proteins regulate gene silencing through small regulatory RNAs, including microRNAs (miRNAs), small-interfering RNAs (siRNAs), and Piwi-interacting RNAs (piRNAs).
  • Understanding the biogenesis pathways of these small RNAs is crucial for deciphering gene regulation.
  • Current analytical tools often focus on specific small RNA classes, limiting comprehensive analysis across diverse organisms.

Purpose of the Study:

  • To develop an integrated computational tool for classifying and interpreting the three major classes of small RNAs: miRNAs, siRNAs, and piRNAs.
  • To provide a user-friendly package that facilitates the characterization of small RNA biogenesis features in non-model organisms.

Main Methods:

  • Development of an R package named MiSiPi.Rna.
  • The package generates plots and statistics for pre-selected genomic loci.
  • Utilizes assembled genomes and small RNA sequencing data for analysis.

Main Results:

  • MiSiPi.Rna enables the characterization of diverse biogenesis features for miRNAs, siRNAs, and piRNAs.
  • The package requires minimal computational expertise, making it accessible to a broader research community.
  • Facilitates annotation and analysis of Argonaute-associated small regulatory RNAs in various species.

Conclusions:

  • MiSiPi.Rna addresses the need for an integrated tool to analyze multiple small RNA classes.
  • This package will accelerate research on small RNA diversity and function in non-model organisms.
  • Simplifies the study of gene silencing mechanisms mediated by Argonaute proteins.
