[Evolution of regulatory proteins].

R M Medzhitov

    Biokhimiia (Moscow, Russia)
    |January 1, 1991
    PubMed
    Summary

    This study proposes a model for the evolution of signal molecules and receptors. It explores how gene fusion and shuffling create new regulatory proteins for metabolic integration, with tissue-specific alternative splicing generating receptor diversity.
