**Background of CARD18 Recombinant Protein**
CARD18. also known as ICEBERG or pseudo-ICE, is a member of the caspase recruitment domain (CARD)-containing protein family, which plays critical roles in apoptosis, inflammation, and immune regulation. It functions as a regulatory protein by modulating caspase activation, particularly caspase-1. a key enzyme involved in the maturation of pro-inflammatory cytokines (e.g., IL-1β, IL-18) and pyroptotic cell death. Structurally, CARD18 contains a CARD domain that enables interaction with other CARD-containing proteins, such as caspase-1 and NLRP3 inflammasome components.
CARD18 acts as a decoy or inhibitory protein by competitively binding to caspase-1. thereby suppressing inflammasome activity and downstream inflammatory signaling. This regulatory mechanism helps maintain immune homeostasis and prevents excessive inflammation, which is implicated in autoimmune diseases, sepsis, and neurodegenerative disorders. Studies suggest that CARD18 expression is induced by inflammatory stimuli (e.g., TNF-α, IFN-γ) and may serve as a feedback control to limit tissue damage during infections or chronic inflammation.
Recombinant CARD18 protein is produced using expression systems like *E. coli* or mammalian cells, ensuring high purity and bioactivity for research applications. It is widely used in *in vitro* and *in vivo* studies to investigate its role in caspase regulation, inflammasome dynamics, and inflammatory pathways. Dysregulation of CARD18 has been linked to diseases such as rheumatoid arthritis, inflammatory bowel disease, and cancer, highlighting its potential as a therapeutic target. Research on CARD18 recombinant protein continues to advance understanding of immune modulation and may pave the way for novel anti-inflammatory therapies.
