Negative regulator of MYD88- and TRIF-dependent toll- like receptor signaling pathway which plays a pivotal role in activating axonal degeneration following injury. Promotes Wallerian degeneration an injury-induced axonal death pathway which involves degeneration of an axon distal to the injury site. Can activate neuronal death in response to stress. Regulates dendritic arborization through the MAPK4-JNK pathway. 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.
