特异性ab22684 recognises caspase-11 proenzyme (43 kD) and the large (23 kD) and small (10 kD) subunits of the mature enzyme. No crossreactivity with other caspases tested: mouse caspases-1 and 3, human caspases 1 to 10 and 14.
功能Involved in ER-stress induced apoptosis. Cleaves caspase-1 (By similarity). Involved in the activation cascade of caspases responsible for apoptosis execution. Promotes IL-1 beta processing by ICE, so may also have a role in inflammatory responses.
组织特异性Mostly expressed in lung and spleen; weaker in heart and lung; little in liver, skeletal muscle, kidney and testis. Not found in the brain.
序列相似性Belongs to the peptidase C14A family. Contains 1 CARD domain.
翻译后修饰The two subunits are derived from the precursor sequence by a autocatalytic mechanism.
