G-protein-coupled receptors (GCRs) are vital for animal signaling. A new database, GCRDb, organizes GCR sequences and data, aiding biological study through family classification.

Area of Science:

  • Biochemistry
  • Genomics
  • Molecular Biology

Background:

  • G-protein-coupled receptors (GCRs) constitute a large protein family crucial for diverse signaling pathways in animals.
  • Humans possess several thousand GCRs, encoded by a comparable number of genes.

Purpose of the Study:

  • To introduce GCRDb, a novel database for GCR sequences and associated biological data.
  • To detail the database's implementation, data acquisition, and query functionalities.
  • To establish a classification system for GCRs within families as a core feature of the database.

Main Methods:

  • Development of a comprehensive database (GCRDb) for GCRs.
  • Implementation of data collection and query systems.
  • Classification of GCRs into families using accepted mutation parsimony analyses.

Main Results:

  • GCRDb provides a centralized resource for GCR sequence and biological data.
  • The database incorporates a systematic classification of GCRs into families and groups.
  • A table detailing the current composition of GCRDb by family and group is presented.

Conclusions:

  • GCRDb serves as a valuable tool for researchers studying GCR biology.
  • The family-based classification facilitates a structured approach to understanding GCR diversity.
  • The database supports further research into the roles of GCRs in various biological systems.
