Recombinant Rat Metabotropic glutamate receptor 1 (Grm1), partial

1. ERK that interacts with and phosphorylates mGluR1a is involved in the regulation of the trafficking and signaling of mGluR1. PMID: 27796752
2. Fyn binds to mGluR1a at a consensus binding motif located in the intracellular C-terminus (CT) of mGluR1a in vitro. Active Fyn phosphorylates mGluR1a at a conserved tyrosine residue in the CT region. In cerebellar neurons and transfected HEK293T cells, Fyn-mediated tyrosine phosphorylation of mGluR1a is constitutively active and facilitates surface expression of mGluR1a and potentiates mGluR1a postreceptor signaling. PMID: 28948209
3. Under control conditions, mGluR1alpha dimer expression increased between juvenile and adolescence (209-328%), while monomeric levels remained consistent. Dimeric mGluR5 was steadily expressed across all time points; monomeric mGluR5 was present in juveniles, dramatically declining at adolescence and adulthood (-97-99%). PMID: 27721389

23. Results suggest that endogenously expressed mGluR1a and mGluR1b variants assemble into dimeric receptor complexes mGluR1a/b and that this association affects the trafficking of the variants in neurons, namely on the mGluR1b delivery to the dendrites PMID: 25158311
