UniProtKB description: NAD(+) hydrolase, which plays a key role in axonal degeneration following injury by regulating NAD(+) metabolism (PubMed:22678360, PubMed:28334607). Acts as a negative regulator of MYD88- and TRIF-dependent toll-like receptor signaling pathway by promoting Wallerian degeneration, an injury-induced form of programmed subcellular death which involves degeneration of an axon distal to the injury site (PubMed:22678360). Wallerian degeneration is triggered by NAD(+) depletion: in response to injury, it is activated and catalyzes cleavage of NAD(+) into ADP-D-ribose (ADPR), cyclic ADPR (cADPR) and nicotinamide; NAD(+) cleavage promoting axon destruction (PubMed:22678360, PubMed:28334607, PubMed:31439792). Involved in the down-regulation of the tracheal immune response to Gram-negative bacteria (PubMed:22022271). This is likely by mediating Tollo signaling in the tracheal epithelium (PubMed:22022271).
