ASC (PYCARD)

Inflammasome adaptor protein

Expression
Essential for pyrin inflammasome

Role in pathogenesis

ASC is the critical adaptor protein that bridges pyrin to caspase-1. The pyrin inflammasome is ASC-dependent — ASC-deficient mice crossed with FMF knock-in mice show complete ablation of inflammation. Pyrin's N-terminal PYD domain interacts with ASC's PYD domain.
