LIG_BIR_III_4 - These IBMs are found in the N-terminal regions of arthropodal caspase subunits where they mediate the inhibition of activated caspases by binding to conserved surface grooves on type III BIR domains of Inhibitor of Apoptosis Proteins (IAPs). |
| CASP1_DROME | 33 | 37 | Binary | Physicochemical compatibility | Binding of the BIR domain-binding motif of Caspase-1 (Dcp-1) to the BIR domains of Apoptosis 1 inhibitor (th) requires cleavage of Caspase-1 (Dcp-1) at D33, since this results in a functional neo N-terminal motif. BIR domains are found in Inhibitor of Apoptosis Proteins (IAPs) that suppress the activity of activated caspases, either by directly inhibiting caspase catalytic activity, or by targeting caspases for degradation by ubiquitin modification. | details |
| ICE_DROME | 28 | 32 | Binary | Physicochemical compatibility | Binding of the BIR domain-binding motif of Caspase (Ice) to the BIR domains of Apoptosis 1 inhibitor (th) requires cleavage of Caspase (Ice) at D28, since this results in a functional neo N-terminal motif. BIR domains are found in Inhibitor of Apoptosis Proteins (IAPs) that suppress the activity of activated caspases, either by directly inhibiting caspase catalytic activity, or by targeting caspases for degradation by ubiquitin modification. | details |
