Mutational analysis identifies residues crucial for homodimerization of myeloid differentiation factor 88 (MyD88) and for its function in immune cells

Abstract

Background: MyD88 is an adaptor protein that plays a crucial role in the immune response. Results: We identified residues within the TIR domain of MyD88 required for protein self-association. Conclusion: Interference with the surface of homodimerization identified by these residues inhibits MyD88 function. Significance: The inhibition of MyD88 activity could be a good therapeutic strategy for inflammatory and autoimmune diseases. © 2013 by The American Society for Biochemistry and Molecular Biology, Inc.
