How these seemingly opposite cellular functions of AIF are controlled is poorly understood. X-linked inhibitor of apoptosis (XIAP) is an endogenous inhibitor of caspases that also regulates several caspase-independent signaling pathways. The RING domain of XIAP possesses E3 ubiquitin ligase activity, though the importance of this function to signal regulation remains incompletely defined. XIAP binds and ubiquitinates AIF, and in this study, we determined the functional consequences of XIAP-mediated AIF ubiquitination. Unlike canonical ubiquitination, XIAP-dependent AIF ubiquitination did not lead to proteasomal degradation of AIF. Experiments using ubiquitin mutants demonstrated that the XIAP-dependent ubiquitin linkage was not formed through the commonly used lysine 48, suggesting a noncanonical ubiquitin linkage is employed. Further studies demonstrated that only lysine 255 of AIF was a target of XIAP-dependent ubiquitination. Using recombinant AIF, we determined that mutating lysine 255 of AIF interferes with the ability of AIF not only to bind DNA but also to degrade chromatin in vitro. These data indicate that XIAP regulates the death-inducing activity of AIF through nondegradative ubiquitination, further defining the role of XIAP in controlling AIF and caspase-independent cell death pathways."xsd:string |
