Comments
  • FUNCTION: Involved in the activation cascade of caspases responsible for apoptosis execution. Might function by either activating some proteins required for cell death or inactivating proteins necessary for cell survival.
  • CATALYTIC ACTIVITY: Strict requirement for an Asp residue at P1, with 316-asp being essential for proteolytic activity and has a preferred cleavage sequence of Val-Asp-Val-Ala-Asp-|-.
  • SUBUNIT: Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a p18 subunit and a p12 subunit. Interacts with LRDD.
  • INTERACTION:
    P42575:CASP2; NbExp=1; IntAct=EBI-520357, EBI-520342;
    P42575-1:CASP2; NbExp=1; IntAct=EBI-520342, EBI-520357;
    P78560:CRADD; NbExp=3; IntAct=EBI-520342, EBI-520375;
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing. Isoforms differ in the N- and C-termini.
    NameICH-1L
    Isoform IDP42575-1
    Note: Acts as a positive regulator of apoptosis.
    This is the isoform sequence displayed in this entry.
    NameICH-1S
    Isoform IDP42575-2
    Note: Acts as a negative regulator of apoptosis.
    Features which should be applied to build the isoform sequence: VSP_000801, VSP_000802.
  • TISSUE SPECIFICITY: Expressed in larger amounts in the embryonic lung, liver and kidney than in the heart and brain. In the adults higher level expression is seen in the placenta, lung, kidney, pancreas than in the heart, brain, liver and skeletal muscle.
  • PTM: The mature protease can process its own propeptide, but not that of other caspases.
  • SIMILARITY: Belongs to the peptidase C14 family [view classification].
  • SIMILARITY: Contains 1 CARD domain.
