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.

textThe metabotropic glutamate receptors (mGluRs) are members of the group C family of G-protein-coupled receptors (GPCRs) (Pin JP et al, 1995; Conn PJ and Pin JP, 1997). Metabotropic glutamate receptors are characterized by a large N-terminal extracellular domain of approximately 560 amino acids which possesses the glutamate binding domain and confers selectivity for agonists. There are eight mGluRs, 1-8 (Desai MA et al, 1995; Flor PJ et al, 1995; Emile L. et al, 1996; Flor PJ et al, 1995b; Minakami R et al, 1994; Laurie DJ et al, 1997; Wu S et al, 1998 respectively). They can be subdivided into 'groups' according to their sequence homology, signal transduction mechanisms and pharmacological properties. Group I contains mGluR1 and 5; Group II contains mGluR2 and 3; Group III contains mGluR4,6,7 and 8 (Nakanishi S, 1992). Group I receptors activate PLC downstream via coupling to Gq/11. Groups II and III inhibit adenylyl cyclase via coupling to Gi.
Like all glutamate receptors, mGluRs bind to glutamate, an amino acid that functions as an excitatory neurotransmitter. Glutamate is the most abundant excitatory neurotransmitter in the mammalian nervous system.
