obsolete regulation of nitric oxide mediated signal transduction https://github.com/geneontology/go-ontology/issues/26613 true The reason for obsoletion is that this term has been inconsistently used and NO signaling proceeds via cGMP, so the more specific replacement term is preferred. OBSOLETE. Any process that modulates the rate, frequency or extent of nitric oxide mediated signal transduction. Nitric oxide mediated signal transduction is The series of molecular signals mediated by the detection of nitric oxide (NO). biological_process GO:0010749 regulation of nitric oxide-cGMP mediated signal transduction
