Inhibits cell cycle progression at the G1/S border and metaphase/anaphase in CHO cells by inhibiting cyclin B degradation. Also prevents nitric oxide production by activated macrophages by interfering with the transcription of inducible nitric oxide synthase (iNOS; NOS II). Inhibits the proteolysis of IκB-α and IκB-β by the ubiquitin-proteasome complex.

General Information
The calpain (Ca
2+
-dependent proteinase or Ca
2+
-activated neutral protease) system consists of two ubiquitous forms of calpain (m-calpain and µ-calpain), a tissue specific calpain (n-calpain), and a calpain inhibitory protein (calpastatin). The calpain system has been detected in every vertebrate tissue examined, and has been suggested to play a regulatory role in cellular protein metabolism. This regulatory role may have important implications in platelet aggregation and pathologies associated with altered Ca
2+
homeostasis and protein metabolism such as ischemic cell injury and degenerative diseases. Inhibitors of calpain have been shown to block dexamethasone and low-level irradiation induced apoptosis in thymocytes suggesting that calpain has a regulatory or mechanistic role in apoptotic cell death.
m- and µ-calpains are heterodimers consisting of 28 kDa and 80 kDa subunits. The 28 kDa subunit is identical in the two isoforms, but the 80 kDa subunits differ with ~50% sequence similarity. 28 kDa/80 kDa complexes are thought to be inactive proenzymes which, upon binding of Ca
2+
, undergo conformational changes that promotes cleavage of the 28 kDa subunit and results in enzyme activation.
BACKGROUND/TECHNICAL INFORMATION
Immunocytochemical staining of µ-calpain in pig LLC-PK1 cells with Prod. No. ALX-804-051 results in diffuse cytoplasmic staining.
