General Information
Term iNOS-S100A8/A9 complex ID (Ontology) GO:1990657 (Gene Ontology)
Definition A protein complex capable of stimulus-inducible nitric-oxide synthase activity. S-nitrosylates cysteine residues in target proteins, a principal mechanism of nitric oxide (NO)-mediated signal transduction. In mammals consists of NOS2, S100A8 and S100A9. S100A9 acts both as an adaptor linking NOS2 to its target and as a transnitrosylase that transfers the nitric oxide moiety from NOS2 to its target, via its own S-nitrosylated cysteine.[ PubMed:25417112 ]
