symbiont-mediated activation of host signal transduction pathway symbiont-mediated activation of host signal transduction pathway via agonism of host cell surface receptor https://github.com/geneontology/go-ontology/issues/26310 GO:0141134 symbiont-mediated perturbation of host signal transduction pathway via antagonism of host cell surface receptor pg A process in which a symbiont subverts a signal transduction pathway in the host organism by binding to and enhancing the activation of the receptor of the pathway. The host is defined as the larger of the organisms involved in a symbiotic interaction. 2023-12-20T14:49:23Z biological_process
