Structural basis for the prion-like MAVS filaments in antiviral innate immunity.

Crystal structure of human IPS-1/MAVS/VISA/Cardif caspase activation recruitment domain.

REFINEMENT PROTOCOL--rigid body DETAILS--The docking of one X-ray model into a segmented map corresponding to one subunit was first done manually in Chimera, and then optimized using SITUS.

Final data were calculated from three separate datasets from three sessions of data collection. The handedness of the map was determined by cryo-electron tomography (Helical Details: IHRSR).

Objective lens astigmatism was corrected at 100,000x magnification
