CASP4

A gene on chromosome 11q22.2-q22.3 that encodes a protein belonging to the cysteine-aspartic acid protease (caspase) family which, once activated by proteolytic processing, plays a central role in the execution-phase of cell apoptosis, as well as various stages of embryological development. CASP4 is an initiator-type caspase, which is activated by, and interacts with, upstream adaptor molecules through CARD and DED protein–protein interaction domains; it is highly expressed in the lung and spleen.
