Descriptions

Sterile alpha and Toll/interleukin receptor (TIR) motif-containing protein 1 (SARM1) regulates axon degeneration, functioning as a key player in the cellular processes involved in neurodegenerative diseases and nerve injury. The physical interaction between the autoinhibitory Armadillo/HEAT motif (ARM) and catalytic Toll/interleukin-1 receptor (TIR) domains blocks the NAD hydrolase activity of SARM1. The autoinhibited TIR domain is activated upon axon injury, activating its NAD+ hydrolase activity and enabling TIR-dependent neuronal destruction.

5 GO annotations of cellular component

Name Definition
axon The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
dendrite A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
neuron projection A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.
neuronal cell body The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

4 GO annotations of molecular function

Name Definition
NAD+ nucleosidase activity Catalysis of the reaction
NAD+ nucleotidase, cyclic ADP-ribose generating Catalysis of the reaction
signaling adaptor activity The binding activity of a molecule that brings together two or more molecules in a signaling pathway, permitting those molecules to function in a coordinated way. Adaptor molecules themselves do not have catalytic activity.
STAT family protein binding Binding to a member of the signal transducers and activators of transcription (STAT) protein family. STATs are, as the name indicates, both signal transducers and transcription factors. STATs are activated by cytokines and some growth factors and thus control important biological processes including cell growth, cell differentiation, apoptosis and immune responses.

7 GO annotations of biological process

Name Definition
antiviral innate immune response A defense response against viruses mediated through an innate immune response. An innate immune response is mediated by germline encoded components that directly recognize components of potential pathogens.
defense response to virus Reactions triggered in response to the presence of a virus that act to protect the cell or organism.
NAD catabolic process The chemical reactions and pathways resulting in the breakdown of nicotinamide adenine dinucleotide, a coenzyme present in most living cells and derived from the B vitamin nicotinic acid; catabolism may be of either the oxidized form, NAD, or the reduced form, NADH.
negative regulation of MyD88-independent toll-like receptor signaling pathway Any process that stops, prevents, or reduces the frequency, rate, or extent of MyD88-independent toll-like receptor signaling pathway.
positive regulation of receptor signaling pathway via STAT Any process that activates or increases the frequency, rate or extent of receptor signaling pathway via STAT.
response to axon injury Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an axon injury stimulus.
signal transduction The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
