Serine proteinase inhibitor 2

UniProtKB accession:  P07385

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Viral serpin that inhibits both cysteine and serine proteinases involved in the regulation of host inflammatory and apoptosis processes (PubMed:10975564). Major anti-apoptotic protein which inhibits both intrinsic and extrinsic pathways and strongly cleaves host CASP1 and CASP8 but is a rather poor inhibitor of host CASP3 (PubMed:10903953). Prevents the proteolytic activity of host interleukin-1-beta converting enzyme (ICE) and ICE-like enzymes. Can also block apoptosis through host tumor necrosis factor (TNF) receptor.
