Specificity
This antibody recognises rat metabotropic glutamate receptor 1a (mGluR1a). The metabotropic glutamate receptors have been organised into three groups. mGluR5 and mGluR1 make up group I which, when activated, stimulates phospholipase C and activates protein kinase C to hydrolyse phosphoinositide phospholipids in the cell membrane. Group I mGluRs, but not other groups, are activated by 3, 5-dihydroxyphenylglycine (DHPG).
