Chain A,B   (SPI2_CWPXB | P07385)
molecular function
    GO:0004869    cysteine-type endopeptidase inhibitor activity    Stops, prevents or reduces the activity of a cysteine-type endopeptidase, any enzyme that hydrolyzes peptide bonds in polypeptides by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile.
    GO:0030414    peptidase inhibitor activity    Stops, prevents or reduces the activity of a peptidase, any enzyme that catalyzes the hydrolysis peptide bonds.
biological process
    GO:0039526    modulation by virus of host apoptotic process    Any process in which a virus modulates the frequency, rate or extent of apoptosis of infected host cells.
    GO:0010466    negative regulation of peptidase activity    Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins.
    GO:0039650    suppression by virus of host cysteine-type endopeptidase activity involved in apoptotic process    Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of host caspase activity. Caspases are cysteine-type endopeptidases which contribute to the apoptotic process.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0030430    host cell cytoplasm    The cytoplasm of a host cell.
