RNA binding proteins can be important modulators of mRNA stability, a critical process that determines the ultimate cellular levels of mRNAs and their encoded proteins. The tristetraprolin or TTP family of RNA binding proteins appeared early in the evolution of eukaryotes, and has persisted in modern eukaryotes. The domain structures and biochemical functions of family members from widely divergent lineages are remarkably similar, but their mRNA ?targets? can be quite different, even in closely related species. Recent gene knockout studies in species as distantly related as plants, flies, yeasts and mice have demonstrated crucial roles for these proteins in a wide variety of physiological processes. Inflammatory and hematopoietic phenotypes in mice have suggested potential therapeutic approaches for analogous human disorders.
