Anti-Sarm1

Protein function: NAD(+) hydrolase, which plays a key role in axonal degeneration following injury by regulating NAD(+) metabolism (PubMed:25818290, PubMed:26686637, PubMed:27735788, PubMed:32312889). 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:21555464, PubMed:22678360, PubMed:25818290, PubMed:26423149, PubMed:26686637). Wallerian degeneration is triggered by NAD(+) depletion: in response to injury, SARM1 is activated and catalyzes cleavage of NAD(+) into ADP-D- ribose (ADPR), cyclic ADPR (cADPR) and nicotinamide, NAD(+) cleavage promoting cytoskeletal degradation and axon destruction (PubMed:28334607). Also able to hydrolyze NADP(+), but not other NAD(+)-related molecules. Can activate neuronal cell death in response to stress (PubMed:19587044). Regulates dendritic arborization through the MAPK4-JNK pathway (PubMed:17724133, PubMed:21555464). Involved in innate immune response: inhibits both TICAM1/TRIF- and MYD88-dependent activation of JUN/AP-1, TRIF-dependent activation of NF-kappa-B and IRF3, and the phosphorylation of MAPK14/p38 (PubMed:21555464).
