1 c-Jun N-terminal kinase (JNK)-mediated phosphorylation of SARM1 regulates NAD+ cleavage activity to inhibit mitochondrial respiration. NAD sterile alpha and TIR motif containing 1 Homo sapiens
2 Sterile alpha and Toll/interleukin receptor motif-containing protein 1 (SARM1) has been attracting much attention as an important molecule for inducing axonal degeneration and neuronal cell death by causing loss of NAD (NADH). nad (nadh) sterile alpha and TIR motif containing 1 Homo sapiens
3 Sterile alpha and Toll/interleukin receptor motif-containing protein 1 (SARM1) has been attracting much attention as an important molecule for inducing axonal degeneration and neuronal cell death by causing loss of NAD (NADH). nad (nadh) sterile alpha and TIR motif containing 1 Homo sapiens
4 Here, we report that NAD+ cleavage activity of SARM1 is regulated by its own phosphorylation at serine 548. NAD sterile alpha and TIR motif containing 1 Homo sapiens
5 Here, we report that NAD+ cleavage activity of SARM1 is regulated by its own phosphorylation at serine 548. Serine sterile alpha and TIR motif containing 1 Homo sapiens
6 The phosphorylation of SARM1 was mediated by c-jun N-terminal kinase (JNK) under oxidative stress conditions, resulting in inhibition of mitochondrial respiration concomitant with enhanced activity of NAD+ cleavage. NAD sterile alpha and TIR motif containing 1 Homo sapiens
7 Nonphosphorylatable mutation of Ser-548 or treatment with a JNK inhibitor decreased SARM1 activity. Serine sterile alpha and TIR motif containing 1 Homo sapiens
8 These results indicate that JNK-mediated phosphorylation of SARM1 at Ser-548 is a regulator of SARM1 leading to inhibition of mitochondrial respiration. Serine sterile alpha and TIR motif containing 1 Homo sapiens
9 These results indicate that JNK-mediated phosphorylation of SARM1 at Ser-548 is a regulator of SARM1 leading to inhibition of mitochondrial respiration. Serine sterile alpha and TIR motif containing 1 Homo sapiens
