Western blot analysis of extracts from C6(lane 2(20μg) ,NIH/3T3(lane 3(20μg) and Hela(lane 4(20ug)using Caspase 11 Antibody (HY-P80588) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
Background

Function
Caspase-11 is a murine inflammatory caspase that drives the noncanonical inflammasome response to cytosolic lipopolysaccharide (LPS) from Gram-negative bacteria[1][2]. Mechanistically, activated caspase-11 cleaves gasdermin D (GSDMD), producing an N-terminal fragment that promotes pyroptosis, IL-1β maturation, and lethal LPS responses[1]. In intestinal epithelial defense, caspase-11 deficiency increases Salmonella Typhimurium epithelial colonization, while human caspase-4 depletion similarly increases bacterial colonization in polarized epithelial monolayers[3]. In kidney injury models, caspase-11/GSDMD signaling promotes tubular epithelial pyroptosis, urinary IL-18 excretion, renal functional deterioration, and podocyte injury under diabetic or acute injury conditions[4][5]. Compared with canonical inflammasomes that activate caspase-1 through NLR or PYHIN sensors, caspase-11 and human caspase-4/5 act as noncanonical intracellular LPS sensors[2][6]. For experimental applications, cardiolipin selectively blocks caspase-4/11-dependent cell death by preventing LPS binding, while maclurin suppresses caspase-11 and GSDMD activation in macrophages and improves acute lethal sepsis outcomes in mice[7][8].

Expression
Tissue_specificity:Widely expressed, including in thymus, lung and spleen (at protein level) . Very low levels, if any, in the brain
Induction:Up-regulated by LPS and E.coli (PubMed:10986288, PubMed:22002608, PubMed:26375259, PubMed:8702803) . In LPS-induced lung inflammation, markedly up-regulated after 6 hours of treatment and decreases at 24 hours. The induction is dependent upon DDIT3/CHOP-mediated ER stress (at protein level) (PubMed:16670335) . In the spleen and in bone marrow-derived macrophages, up-regulated by poly (I:C) , a synthetic analog of double-stranded RNA (at protein level) (PubMed:26320999, PubMed:26375259) . Also induced by IFNG and interferon-alpha. Up-regulated by R848, a TLR7 synthetic activator, and Pam3CysK4, a synthetic activator of TLR1/TLR2 (PubMed:26375259) -
Isoforms & Post-Translational Modification
P70343 has 2 isomers: P70343-1: 42742 Da (predicted); P70343-2: 13746 Da (predicted).
In response to activation signals, undergoes autoproteolytic cleavage and activation;(Microbial infection) ADP-riboxanation by S.flexneri OspC3 blocks CASP4 autoprocessing, preventing CASP4 activation and ability to recognize and cleave GSDMD, thereby thwarting the inflammasome/pyroptosis-mediated defense -
Subunit
Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 20 kDa (Caspase-4 subunit p20) and a 10 kDa (Caspase-4 subunit p10) subunit (PubMed:32109412). Upon direct LPS-binding, forms large homooligomers, resulting in its activation (PubMed:25119034). These oligomers are often referred to as 'non-canonical inflammasomes' (PubMed:25119034). In its precursor form, interacts with TMEM214; this interaction is required for association with the endoplasmic reticulum membrane (By similarity). Interacts with CASP1 (By similarity). Interacts with NOD2 (By similarity). Interacts with Serpinb1a, Serpinb1b and Serpinb1c; these interactions regulate CASP4 activity (By similarity)
