Background:

G-quadruplexes are four-stranded nucleic acid structures.
They exhibit high thermal stability, particularly with monovalent cations.
Emerging evidence links G-quadruplexes to gene transcription and translation regulation.

Purpose of the Study:

To create a centralized, community-focused website for G-quadruplex information.
To provide a comprehensive database of predicted G-quadruplexes across genomes.
To offer tools for predicting G-quadruplex thermal stability and collecting experimental data.

Main Methods:

Development of a predictive algorithm for identifying G-quadruplexes.
Creation of the QuadDB database integrating predicted structures.
Implementation of the QuadPredict server for stability predictions and data deposition.

Main Results:

A detailed database (QuadDB) of predicted G-quadruplexes in human and other genomes.
A publicly accessible QuadPredict server for thermal stability predictions.
A repository for experimental G-quadruplex data from the research community.

Conclusions:

The QuadDB website and QuadPredict server provide a valuable resource for G-quadruplex research.
Facilitates the investigation of gene hypotheses related to G-quadruplex functions.
Promotes community engagement and data sharing in the G-quadruplex field.
