Preliminary X-ray crystallographic studies of the TIR domain of human Toll-like receptor 6

초록

Toll-like receptor (TLR) proteins have been identified and shown to play a role in the innate immune response. TLR6 associated with TLR2 can recognize diacylated lipoprotein. In this study, the human TLR6 TIR domain corresponding to amino acids 640–796 was overexpressed in Escherichia coli using engineered C-terminal His tags. The TLR6 TIR domain was then purified to homogeneity and crystallized at 20°C. Finally, X-ray diffraction data were collected to a resolution of 2.2 Å from a crystal belonging to space group C2, with unit-cell parameters a = 127.60, b = 44.20, c = 75.72 Å, β = 118.89°
