General description
Caspase 12 is a protein that belongs to a family of enzymes called caspases that cleave their substrates at C-terminal aspartic acid residues. The human caspase 12 gene is localized at a single locus within the caspase 1/ICE gene cluster on chromosome 11q22. The functionality is lost in humans and they cannot play a role in Alzheimer′s disease. Caspase-12 is detected in endoplasmic reticulum (ER), plays a role in ER-mediated apoptosis and inflammatory caspase activation pathway.
Monoclonal Anti-Caspase 12 (rat IgG2a isotype) is derived from the 14F7 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from CD rats immunized with a recombinant mouse caspase 12. Caspases (cysteine-requiring aspartate protease) are a family of proteases that share similarities in amino acid sequences, structure and substrate specificity. Caspase 12 is ubiquitously expressed in mouse tissues, at high levels in muscle, liver and kidney and at moderate levels in brain, where it is present in cortical neurons, Purkinje cells, brainstem neurons, and olfactory neurons.
Specificity
Recognizes full length and possibly truncated p20 caspase 12.
Immunogen
recombinant mouse caspase 12 (residues 95-318).
application
Monoclonal Anti-Caspase 12 has been used in immunoblotting and immunocytochemistry (4% paraformaldehyde-fixed, paraffin-embedded).
Biochem/physiol Actions
Caspase 12 (CASP12) has a downregulatory function during infection and may play a role in protection against inflammatory disease. It is associated with rheumatoid arthritis in African-Americans. Caspase-12 inhibits caspase-1 activation and is associated with susceptibility factor for bacterial sepsis but does not influence the susceptibility to Candida sepsis.
Murine caspase 12 (CASP12) is activated during endoplasmic reticulum stress and activates other caspases which act on substrates, ultimately leading to apoptosis. The protein has been shown to be activated during progression of retinal degeneration in animal models. In mice models, CASP12 has been shown to cause neuronal death resulting from ischemia/reperfusion. Casp12 might stimulate nuclear factor-κB (NF-κB) by directing the post-translational degradation of inhibitor of kappa B (IκBα). Overexpression of caspase 12 induces apoptosis, which is inhibited by the pan caspase inhibitor carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]- fluoromethyl ketone (z-VAD-FMK).
