Recently, receptor interacting protein (RIP)-1 has been recognized as an intracellular sensor at the crossroads of apoptosis, necroptosis, and cell survival. To reveal when this crucial molecule originated and how its function in integrating stress signals evolved, in this study we report on two RIP1 homologs in Chinese amphioxus (Branchiostoma belcheri tsingtauense), designated B. belcheri tsingtauense RIP1a and B. belcheri tsingtauense RIP1b. Phylogenetic analysis indicates that they are generated by domain recombination and lineage-specific duplication. Similar to human RIP1, both B. belcheri tsingtauense RIP1a and B. belcheri tsingtauense RIP1b activate NF-κB in a kinase activity-independent manner and induce apoptosis through the Fas-associated death domain protein-caspase cascade. Moreover, we found that the natural point mutation of Q to I in the RIP homotypic interaction motif of B. belcheri tsingtauense RIP1a provides negative feedback for amphioxus RIP1-mediated signaling. Thus, our study not only suggests that RIP1 has emerged as a molecular switch in triggering cell death or survival in a basal chordate, but also adds new insights into the regulation mechanisms of RIP1-related signaling, providing a novel perspective on human diseases mediated by RIP1.
