    Summary

    This study introduces a novel classification system for cell receptors based on evolutionary and biological traits, revealing a coevolution between ligand-receptor interactions and a dynamic biological code. This framework aids in understanding cellular information transduction and receptor function.

    Area of Science:

    • Biochemistry
    • Molecular Biology
    • Systems Biology

    Background:

    • Cell receptors play a crucial role in biological information processing.
    • Existing classification methods for ligand-receptor units are limited.
    • Understanding receptor function is key to cellular and organismal integrity.

    Purpose of the Study:

    • To propose a novel classification system for cell receptors based on evolutionary and biological characteristics.
    • To introduce a systems theory for information transduction at receptors.
    • To explore the relationship between the dynamic code and the genetic code.

    Main Methods:

    • Analysis of evolutionary and biological characteristics of ligand-receptor units.
    • Categorization of receptors into original families based on molecular and protein structure.
    • Introduction of a systems theory for receptor information transduction.

    Main Results:

    • A new classification framework for ligand-receptor units is proposed.
    • Two primary receptor classes are identified: receptors for cyclic hydrophobic compounds and membrane receptors.
    • A coevolution between ligand-receptor dynamics and the biological dynamic code is revealed.
    • A systems theory for information transduction, including sensitivity modulation, is presented.

    Conclusions:

    • The proposed classification based on molecular and protein structure offers a useful approach to understanding receptors.
    • The dynamic code, distinct from the genetic code, governs biological information patterns.
    • The systems theory provides a framework for analyzing receptor function and information transduction.
