negatively regulates negative regulation of opsin-mediated signaling pathway negative regulation of phospholipase C-activating phototransduction signaling pathway https://github.com/geneontology/go-ontology/issues/27505 Wikipedia:Visual_phototransduction Any process that stops, prevents or reduces the frequency, rate or extent of phospholipase C-activating phototransduction signaling pathway. Activated rhodopsin (R*) is inactivated by a two-step process: first, R* is phosphorylated by rhodopsin kinase which lowers the activity of R*. Second, the protein arrestin binds to phosphorylated R* to de-activate it.
