DIAP1_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 Dronc, and effector caspases Drice and Dcp-1. Acts as a Nedd8-E3 ubiquitin-protein ligase for Drice. Suppresses apoptosis by targeting the apoptosome for ubiquitination and inactivation. Plays an important role in cell motility. Overexpression suppresses rpr and hid-dependent cell death in the eye. Interaction of Diap1 with Dronc is required to suppress Dronc-mediated cell death through Diap1-mediated ubiquitination of Dronc. Acts as a positive regulator of Wnt signaling.[1][2][3][4][5][6]
