RAIDD (RIP-associated ICH-1/CED-3-homologous protein with a death domain), is a dual-domain adaptor protein that is constitutively expressed in many tissues (1, 2). RAIDD has an N-terminal caspase recruitment domain (CARD) that interacts with the CARD of caspase-2, and a C-terminal death domain (DD) that interacts with the DD in PIDD (p53-induced protein with a death domain) (3). RAIDD has been shown to mediate the recruitment of CASPASE-2 to tumor necrosis factor receptor-1 (TNF-R1) signalling complex through RIP kinase. Apart from its established role in apoptosis, RAIDD may have an additional function in cell differentiation, supported by its expression in developing organs derived from the ectoderm, like heart and kidney. In developing heart and kidney RAIDD expression patterns are reported to overlap with known zones of cell death suggesting RAIDD may be involved in apoptosis-mediated remodeling (1).
