Protein attributes

Sequence length	377 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in the activation cascade of caspases responsible for apoptosis execution. Cleaves caspase-1.
Catalytic activity	Strict requirement for Asp at the P1 position. It has a preferred cleavage sequence of Tyr-Val-Ala-Asp-|- but also cleaves at Asp-Glu-Val-Asp-|-.
Subunit structure	Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a small and a large subunit By similarity.
Tissue specificity	Widely expressed, with highest levels in spleen and lung. Moderate expression in heart and liver, low expression in skeletal muscle, kidney and testis. Not found in the brain.
Post-translational modification	The two subunits are derived from the precursor sequence by an autocatalytic mechanism or by cleavage by Caspase-8.
Sequence similarities	Belongs to the peptidase C14A family. Contains 1 CARD domain.
