Enzyme Function FUNCTION: Multi-functional protein which regulates not only caspases and apoptosis, but also acts as an E3 ubiquitin-protein ligase mediating ubiquitination and subsequent proteasomal degradation of its target proteins. Acts as a direct caspase inhibitor. A key apoptotic suppressor in eggs. Acts as a positive regulator of Wnt signaling. {ECO:0000250}.

Modified Residue
Post Translational Modification PTM: Degraded in a 2-step mechanism; a caspase-independent first step and a caspase-dependent second step. Stabilized indirectly by MAPK, which acts to delay caspase activation, rather than directly phosphorylating xiap. {ECO:0000250|UniProtKB:A5D8Q0}.
