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 Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.SUBUNIT G proteins are composed of 3 units, alpha, beta and gamma.SUBCELLULAR LOCATION Retinal rod outer segment.SIMILARITY Belongs to the G protein gamma family.CAUTION In PubMed:3917402 the authors propose that Cys-36 and Cys-37 are disulfide bonded because they could not be observed during peptide sequencing, but were observed after reduction by dithiothreitol and reaction with labeled iodoacetamide. The crystallographic structures do not support these cysteines being disulfide bonded. Artifactual oxidation and some other cysteine modifications might be consistent with these observations.
