We previously observed that the TIR domain of MAL (MAL) forms filaments in vitro and induces formation of crystalline higher-order assemblies of the MyD88 TIR domain (MyD88). These crystals are too small for conventional X-ray crystallography, but are ideally suited to structure determination by microcrystal electron diffraction (MicroED) and serial femtosecond crystallography (SFX). Here, we present MicroED and SFX structures of the MyD88 assembly, which reveal a two-stranded higher-order assembly arrangement of TIR domains analogous to that seen previously for MAL. We demonstrate via mutagenesis that the MyD88 assembly interfaces are critical for TLR4 signaling in vivo, and we show that MAL promotes unidirectional assembly of MyD88. Collectively, our studies provide structural and mechanistic insight into TLR signal transduction and allow a direct comparison of the MicroED and SFX techniques.
温度: 310 K / 手法: batch mode 詳細: MAL TIR (0.5-3 micromolar) was incubated with MyD88 TIR domain (60-100 micromolar) in 10 millimolar HEPES at pH 7.5-8, 150 millimolar NaCl at 298-310K.
