STRUCTURE AND MECHANISM OF INTERLEUKIN-1BETA CONVERTING ENZYME

Structural highlights

1ice is a 3 chain structure with sequence from Homo sapiens. The August 2004 RCSB PDB Molecule of the Month feature on Caspases by David S. Goodsell is 10.2210/rcsb_pdb/mom_2004_8. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[CASP1_HUMAN] Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.^[1] ^[2]

Publication Abstract from PubMed

Interleukin-1 beta converting enzyme (ICE) processes an inactive precursor to the proinflammatory cytokine, interleukin-1 beta, and may regulate programmed cell death in neuronal cells. The high-resolution structure of human ICE in complex with an inhibitor has been determined by X-ray diffraction. The structure confirms the relationship between human ICE and cell-death proteins in other organisms. The active site spans both the 10 and 20K subunits, which associate to form a tetramer, suggesting a mechanism for ICE autoactivation.
