ICEBERG Proteins and Enzymes

ICEBERG, also known as Caspase recruitment domain-containing protein 18, is a 90 amino acid protein that is 10 kDa, most often expressed in the heart and placenta, down-regulates the release of IL1B, and by interacting with caspase-1 and preventing its association with RIP2 inhibits the generation of IL-1-beta. This protein is being studied for its involvement in chronic lymphocytic leukemia. The ICEBERG protein has been linked to the NOD-like receptor signaling pathway where it interacts with CASP1, CARD8, CARD16, and CARD17.
