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 Retina-specific kinase involved in the signal turnoff via phosphorylation of rhodopsin (RHO), the G protein- coupled receptor that initiates the phototransduction cascade (PubMed:12686556, PubMed:16675451, PubMed:21299498). This rapid desensitization is essential for scotopic vision and permits rapid adaptation to changes in illumination (By similarity). May play a role in the maintenance of the outer nuclear layer in the retina (By similarity).CATALYTIC ACTIVITY L-threonyl-[rhodopsin] + ATP = O-phospho-L-threonyl-[rhodopsin] + ADP + H(+)CATALYTIC ACTIVITY L-seryl-[rhodopsin] + ATP = O-phospho-L-seryl-[rhodopsin] + ADP + H(+)ACTIVITY REGULATION Inhibited by RCVRN, which prevents the interaction between GRK1 and RHO (PubMed:12686556, PubMed:21299498). Inhibition is calcium-dependent (PubMed:12686556).SUBUNIT Interacts (via N-terminus) with RCVRN (via C-terminus); the interaction is Ca(2+)-dependent (PubMed:16675451, PubMed:17020884, PubMed:21299498, PubMed:24189072, PubMed:26584024). Interacts (when prenylated) with PDE6D; this promotes release from membranes (PubMed:14561760). May form a complex composed of RHO, GRK1 and RCVRN in a Ca(2+)-dependent manner; RCVRN prevents the interaction between GRK1 and RHO (PubMed:17020884).INTERACTION Subcellular location is not affected by light or dark conditions.TISSUE SPECIFICITY Rod outer segments of retina photoreceptor cells (at protein level) (PubMed:1527025, PubMed:1656454, PubMed:1730692). Retina (PubMed:1656454).PTM Autophosphorylated, Ser-21 is a minor site of autophosphorylation compared to Ser-488 and Thr-489. Phosphorylation at Ser-21 is regulated by light and activated by cAMP (Probable).PTM Farnesylation is required for full activity.SIMILARITY Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. GPRK subfamily.
