Background

Caspase-1, also known as interleukin-1-beta (IL-1beta) -converting enzyme (ICE), is a member of the cysteine-aspartic protease (caspase) family (1). The caspase family are aspartic proteolytic enzymes that play a key role in apoptotic cell death and inflammation (1). Caspase-1 is synthesized as an inactive proenzyme with a theoretical molecular weight of approximately 45 kDa and is 404 amino acids (aa) in length. The caspase-1 protein structure contains an N-terminal CARD (caspase recruitment domain), a large 20kDa P20 subunit (aa 120-297), and a small 10kDa P10 subunit (aa 317-404) (1, 2). The proenzyme undergoes cleavage at aspartic acid (Asp) residues to produce the active caspase-1 enzyme which exists as a heterotetramer (homodimer of the P20 and P10 heterodimers) (2). Inflammasome complexes sense various microbial and endogenous signals, including ligand-receptor interaction and growth factor deprivation, which results in the processing of pro-caspase to active caspase-1 (3, 4).The active caspase-1 is responsible for the cleavage and maturation of pro-inflammatory cytokines IL-1beta and IL-18, and promotes an inflammatory form of cell death induced by bacterial pathogens called pyroptosis (3, 4). Mature IL-1beta has a role in the immune reaction and recruiting inflammatory cells to the site of infection while IL-18 plays a role in interferon-gamma production and promotes cytolytic activity in natural killer cells (4).

Given the role of IL-1beta in inflammation, it makes sense that many diseases and pathologies have been associated with dysregulation of caspase-1 activation and the inflammasome (3, 4). The inflammasome is a multiprotein complex comprised of Nod-like receptor (NLR) family members and the adapter ASC (apoptosis-associated speck-like protein containing a CARD) which are crucial for capase-1 activation (3-5). For instance, the neuronal apoptosis inhibitory protein (NAIP)/NLRC4 inflammasome has been associated with colorectal cancer, breast cancer, and glioma pathogenesis (5). Caspase-1 activation and mutations in the inflammasome have also been linked to Chron's disease and Alzheimer's disease (4). In addition to immune and inflammatory related disorder, the inflammasome has been linked to metabolic and obesity related disorders including diabetes and cardiovascular disease (6). Finally, caspase-1 deficient mice exhibit enhanced epithelial cell proliferation in the colon, increased tumor formation, and reduced apoptosis (1). A more thorough understanding of the inflammasome-caspase-1 signaling pathway will be important for understanding disease pathology and potential therapeutic development.

Alternative names for caspase-1 includes CASP1, CASP1 nirs variant 1, EC 3.4.22.36, ICE, IL-1 beta-converting enzyme, IL1BC, IL1BCE, IL1B-converstase, interleukin-1 beta convertase, and p45.

FAQs for Caspase-1 Antibody (NB100-56565). (Showing 1 - 2 of 2 FAQs).

  1. We have purchased "NB100-56565 Caspase-1 Antibody (14F468)" for our experiments. It is mentioned in product data sheet that it can detect the cleave forms of Caspase-1 as well. Can you kindly tell me the expected size of cleaved subforms on WB, so that I could be sure about my results?
    • The antibody will recognize full-length Caspase-1 and cleaved caspase-1 forms that retain amino acids 371-390 of the Caspase-1 protein. In short this antibody can recognize any protein species, after processed by protease in vivo, that contains the region of a.a. 371 - 390.
  2. We are interested in your items, NB100-56565 and NB100-56564 and I would like to use them for recognizing the cleaved form of Caspase-1. Would you please let me know if NB100-56565 and NB100-56564 recognize the Caspase-1 p10 or p20? If so, could you please provide me any supporting data of them?
    • For NB100-56565 & NB100-56564 it will recognize the full length form and the p10 as the immunogen. A synthetic peptide corresponding to amino acids 371-390 RKVRFSFEQPDGRAQMPTTE of human caspase-1 was used as immunogen. The p10 subunit is aa 307-404. If you need an antibody to the p20 subunit:http://www.novusbio.com/Caspase-1-Antibody_NBP1-45433.html. This will bind to the the region around aa 132. The p20 subunit is aa 120-297.
