Background Information
Caspase-3 (also know as CPP32, Yama and apopain) is a member of the caspase family of cysteine proteases. Caspase-3 exists in cells as an inactive 32 kDa proenzyme. Proteolytic processing of this inactive proenzyme generates the 17 kD and 12 kD subunits which, when assembled as a tetramer (a pair of heterodimers), form the active caspase. Cascades of caspase activation have been shown to be key signal-transducing events in apoptosis. Procaspase-3, like other procaspases with short N-terminal prodomains, is considered to be a downstream or “effector” enzyme. Pro-caspase-3 can be cleaved and activated by caspase-8 and –10 which are themselves activated through interaction with death ligand receptor/adapter protein complexes (e.g., Fas/FADD). Procaspase-3 is also processed by caspase-9, the apical caspase that is activated by binding to the Apaf-1/cytochrome c/ATP “apoptosome”. Thus, activation of procaspase-3 stands at a point of convergence for the two major types of apoptosis signaling pathways-those linked to cell surface death receptors and those linked to mitochondrial release of cytochrome c. The recombinant Procaspase-3 (1183P-5) is produced by expression of a human cDNA in E. coli. The purified protein is highly activatable by treatment with active recombinant caspase-8 (1088-25, -100). We routinely test the activation using 10-30 ng of the procaspase-3 treated with 0.1-0.5 units of the active recombinant caspase-8 in 100 µl of Reaction Buffer (1068-20) for 30 minutes. Activation of procaspase-3 can be monitored using the Caspase-3 Fluorometric and Colorimetric Assay Kits (K105 and K106).

Additional description
Human and some mouse caspases are active in apoptosis and cell death and even in necrosis and inflammation. CASP Gene and orthologous enzymes have been identifies successfully in the signal transduction cascade and pathways.

Test
Mouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.
