Guanylyl cyclase-activating protein 2

UniProtKB accession:  P51177

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Stimulates two retinal guanylyl cyclases (GCs) GUCY2D and GUCY2F when free calcium ions concentration is low, and inhibits GUCY2D and GUCY2F when free calcium ions concentration is elevated (PubMed:7665624). This Ca(2+)-sensitive regulation of GCs is a key event in recovery of the dark state of rod photoreceptors following light exposure (PubMed:9651312). May be involved in cone photoreceptor response and recovery of response in bright light (By similarity).
