Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

4.2K
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...

Gene Families01:57

Gene Families

9.0K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Gene Duplication and Divergence

6.3K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Globular and Fibrous Proteins02:21

Globular and Fibrous Proteins

44.2K
Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • G-quadruplexes (G4s) are crucial 3D structures in DNA and RNA with implications in biological mechanisms and therapeutic development.
  • While G4s in humans are well-studied, research in other species is limited, despite predictions showing their presence across all living kingdoms.
  • Existing databases catalog G4s by structure, protein interactions, or genomic location, but lack comprehensive transcriptome data.

Purpose of the Study:

  • To introduce the GAIA database, a novel online resource for exploring G-quadruplexes.
  • To provide user-friendly access to G4 locations within the transcriptome of diverse species.
  • To facilitate research on G4s by consolidating and presenting previously inaccessible data.

Main Methods:

  • Development of the GAIA web interface for online data accessibility.
  • Integration of predicted G4 structures from various species.
  • Implementation of query and filtering functionalities for user-driven data exploration.

Main Results:

  • GAIA successfully aggregates and presents G4 location data within the transcriptome.
  • The database allows users to query and filter G4s across a wide range of species.
  • GAIA serves as a centralized, accessible platform for G4 research.

Conclusions:

  • The GAIA database significantly enhances the study of G-quadruplexes by providing crucial transcriptome location data.
  • This resource is expected to accelerate research into the biological functions and therapeutic applications of G4s.
  • GAIA represents a valuable tool for the scientific community studying G4 structures across diverse organisms.
