Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

4.0K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Conserved Binding Sites

4.2K
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Conservation of Protein Domains Over Different Proteins

10.9K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Gene Evolution - Fast or Slow?

7.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

5.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Area of Science:

  • Computational Biology
  • Bioinformatics
  • Genomics

Background:

  • Distinguishing coding from non-coding DNA is a fundamental challenge in computational biology.
  • Existing methods like RNAcode excel with sequence conservation but require multiple sequence alignments (MSAs), which are often difficult to obtain.
  • The need for user-friendly tools to identify potential coding regions, especially short ones, is significant.

Purpose of the Study:

  • To introduce RNAcode-Web, a novel web service simplifying the detection of coding sequences.
  • To provide a user-friendly platform that automates the generation of necessary multiple sequence alignments for RNAcode.
  • To enhance accessibility for non-expert users to investigate genomic regions for unannotated coding potential.

Main Methods:

  • The service automates the retrieval and preparation of homologous sequences from the NCBI database.
  • It constructs multiple sequence alignments (MSAs) required as input for the RNAcode algorithm.
  • RNAcode-Web integrates these automated steps, requiring only a single target nucleotide sequence as input.

Main Results:

  • RNAcode-Web successfully automates the entire pre- and post-processing pipeline for coding sequence detection.
  • The service significantly reduces user overhead, making advanced analysis accessible to non-experts.
  • It facilitates the identification of previously unannotated coding regions, such as small peptides or alternative introns.

Conclusions:

  • RNAcode-Web democratizes the use of powerful sequence conservation-based methods for coding region identification.
  • The automated workflow streamlines the process, enabling efficient exploration of genomic data.
  • This tool empowers researchers to easily investigate potential coding elements within their sequences of interest.
