Background: Caspase family of cysteine proteases has been shown to play a key role in apoptosis. Mammalian caspases can be subdivided into three functional groups: initiator caspases (Caspase 2, 8, 9 and 10), executioner caspases (Caspase-3, 6 and 7), and inflammatory caspases (Caspase 1, 4, 5, 11 and 12). Caspase-4 (also known as Ich-4, ICErelII, TX) is a member of the caspase-family of cysteine proteases. The active caspase-4 is a heterotetramer consisting of two large and two small subunits.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the cysteine proteases that plays important roles in apoptosis, cell migration and the inflammatory response. The encoded protein mediates production of pro-inflammatory cytokines by macrophages upon bacterial infection. Mice lacking the encoded protein are resistant to endotoxic shock induced by lipopolysaccharide. A 5-bp deletion encompassing a splice acceptor junction resulting in alternate splicing and a shorter non-functional isoform in certain mouse strains has been described. Although its official nomenclature is "caspase 4, apoptosis-related cysteine peptidase", this gene and its encoded protein have historically been called caspase 11. This gene is present in a cluster of three caspase genes on chromosome 9. [provided by RefSeq, Apr 2015]
Uniprot Description
CASP4: Involved in the activation cascade of caspases responsible for apoptosis execution. Cleaves caspase-1. Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a small and a large subunit. 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. Belongs to the peptidase C14A family. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The Casp4 casp4 (Catalog #AAA9718956) is an Assay Kit and is intended for research purposes only. The product is available for immediate purchase. Caspase 4 Assay Kit (Colorimetric) is based on the hydrolysis of the peptide substrate Ac-LEVD-pNA (acetyl-Leu-Glu-Val-Asp p-nitroanilide) by caspase 4, resulting in the release of the p-nitroaniline (pNA), which can be quantified using a spectrophotometer or a microtiter plate reader at at 405 nm. Researchers should empirically determine the suitability of the Casp4 casp4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Caspase-4, Assay Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
