==Function== | |||
[[http://www.uniprot.org/uniprot/IAP1_DROME IAP1_DROME]] Anti-apoptotic protein which functions as a caspase regulator, using its E3 ubiquitin-protein ligase activity to smother caspase activity. Binds, ubiquitinates and inactivates initiator caspase Nc, and effector caspases ICE and DCP-1. Acts as a NEDD8-E3 ubiquitin-protein ligase for ICE. Suppresses apoptosis by targeting the apoptosome for ubiquitination and inactivation. Plays an important role in cell motility. Overexpression suppresses rpr and W-dependent cell death in the eye. Interaction of th with Nc is required to suppress Nc-mediated cell death; th-mediated ubiquitination of Nc. Acts as a positive regulator of Wnt signaling.<ref>PMID:8548811</ref> <ref>PMID:17397804</ref> <ref>PMID:18259196</ref> <ref>PMID:21145488</ref> <ref>PMID:22304967</ref> <ref>PMID:14517550</ref> | |||
