  • Western blot analysis of extracts from M-spleen (lane 1) and 293T (lane 2) using Caspase-1 p20 antibody. Proteins were transferred to a PVDF membrane and blocked with 5% nonfat powdered milk in PBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (GAPDH, 1/3000) was diluted with 5% nonfat powdered milk in PBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (1/8,000) was incubated for 45min at room temperature.

  • Immunohistochemical analysis of paraffin-embedded human liver tissue using Caspase-1 Antibody (HY-P81232, 1/500). The section was pretreated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked with quick block buffer for 0.5 hours at room temperature, washed with PBS and PBST, and then incubated with the primary antibody overnight at 4℃. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background
Function:Thiol protease involved in a variety of inflammatory processes by proteolytically cleaving other proteins, such as the precursors of the inflammatory cytokines interleukin-1 beta (IL1B) and interleukin 18 (IL18) as well as the pyroptosis inducer Gasdermin-D (GSDMD), into active mature peptides (PubMed:21147462, PubMed:32109412). Plays a key role in cell immunity as an inflammatory response initiator: once activated through formation of an inflammasome complex, it initiates a pro-inflammatory response through the cleavage of the two inflammatory cytokines IL1B and IL18, releasing the mature cytokines which are involved in a variety of inflammatory processes (PubMed:21147462). Cleaves a tetrapeptide after an Asp residue at position P1 (PubMed:21147462). Also initiates pyroptosis, a programmed lytic cell death pathway, through cleavage of GSDMD (PubMed:32109412). In contrast to cleavage of interleukin IL1B, recognition and cleavage of GSDMD is not strictly dependent on the consensus cleavage site but depends on an exosite interface on CASP1 that recognizes and binds the Gasdermin-D, C-terminal (GSDMD-CT) part (PubMed:32109412). Cleaves and activates CASP7 in response to bacterial infection, promoting plasma membrane repair (PubMed:18667412, PubMed:22464733, PubMed:35705808). Upon inflammasome activation, during DNA virus infection but not RNA virus challenge, controls antiviral immunity through the cleavage of CGAS, rendering it inactive (PubMed:28314590). In apoptotic cells, cleaves SPHK2 which is released from cells and remains enzymatically active extracellularly (By similarity)
Subcellular Localization:Cytoplasm; Cell membrane
Expression:
Tissue_specificity:High level expression seen in spleen and lung, low level expression seen in brain, heart, liver, kidney, testis and skeletal muscle
Subunit:Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 20 kDa (Caspase-1 subunit p20) and a 10 kDa (Caspase-1 subunit p10) subunit (PubMed:32109412).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
