Caspase-6 (Active) from Human, Recombinant
Caspase-6 is an enzyme that in humans is encoded by the CASP6 gene. This gene encodes a protein that is a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes that undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This protein is processed by caspases 7, 8 and 10, and is thought to function as a downstream enzyme in the caspase activation cascade. Caspase 6 can also undergo self-processing without other members of the caspase family. Alternative splicing of this gene results in two transcript variants that encode different isoforms. Group: Enzymes. Synonyms: CASP6; MCH2; Caspase-6 (Active); Caspase-6. Caspase 6. Appearance: Liquid. Storage: -80°C.

Caspase-7 from Human, Recombinant
Caspase-7 is a member of the caspase (cysteine aspartate protease) family of proteins, and has been shown to be an executioner protein of apoptosis. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes that undergo proteolytic processing by upstream caspases (caspase-8, -9) at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme in the form of a heterotetramer. The precursor of this caspase is cleaved by caspase 3, caspase 10, and caspase 9. It is activated upon cell death stimuli and induces apoptosis. Alternative splicing results in four transcript variants, encoding three distinct isoforms. Applications: Used to screen caspase inhibitors, study enzyme regulation, determine caspase substrate specificity, or as positive control in caspase activity assays. Group: Enzymes. Synonyms: CASP7; CASP-7; CMH-1; ICE-LAP3; LICE2; MCH3; Caspase-7. Enzyme Commission Number: EC 3.4.22.-. Purity: 90% (SDS-PAGE). Caspase 7. Activity: ~25,000U/mg protein. Appearance: Lyophilized.
