Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Responsible for the synthesis of cyclic GMP (cGMP) in rods and cones of photoreceptors (PubMed:7777544). Plays an essential role in phototransduction, by mediating cGMP replenishment (By similarity). May also participate in the trafficking of membrane-associated proteins to the photoreceptor outer segment membrane (By similarity).CATALYTIC ACTIVITY GTP = 3',5'-cyclic GMP + diphosphateACTIVITY REGULATION Activated by GUCA1B when free calcium ions concentration is low, and inhibited by GUCA1B when free calcium ions concentration is high (PubMed:15772651). Inhibited by RD3 (PubMed:29515371).SUBUNIT Homodimer (By similarity). Interacts with RD3; promotes the exit of GUCY2F from the endoplasmic reticulum and its trafficking to the photoreceptor outer segments (By similarity).SUBCELLULAR LOCATION Retina. Localized exclusively in the outer nuclear layer and inner segments of the rod and cone photoreceptor cells.DOMAIN The protein kinase domain is predicted to be catalytically inactive.PTM There are 9 conserved cysteine residues in sensory guanylate cyclases, 6 in the extracellular domain, which may be involved in intra- or interchain disulfide bonds.SIMILARITY Belongs to the adenylyl cyclase class-4/guanylyl cyclase family.
