Structural analysis of the complement control protein (CCP) modules of GABA(B) receptor 1a: only one of the two CCP modules is compactly folded.
TLDR
It is shown that the two CCP modules of GABA(B) R1a have strikingly different structural properties, reflecting their different functions, including a strong similarity to previously determined CCP module structures in the regulators of complement activation.
Metabotropic Glutamate 1α and Adenosine A1 Receptors Assemble into Functionally Interacting Complexes*
TLDR
The results provide a molecular basis for adenosine/glutamate receptors cross-talk and open new perspectives for the development of novel agents to treat neuropsychiatric disorders in which abnormal glutamatergic neurotransmission is involved.
Identification of Molecular Determinants That Are Important in the Assembly of N-Methyl-d-aspartate Receptors*
TLDR
Results suggest the residues N-terminal of residue 380 are important for the association of NR2A with NR1a and that the complete N-Terminal domain of the NR 1a subunit is required for oligomerization with NR2a.
Homer-1c/Vesl-1L Modulates the Cell Surface Targeting of Metabotropic Glutamate Receptor Type 1α: Evidence for an Anchoring Function
TLDR
The results suggest that Homer-1c increases the cell surface expression of the metabotropic glutamate receptor type 1alpha by increasing its retention in the plasma membrane.
Desensitization and internalization of metabotropic glutamate receptor 1a following activation of heterologous Gq/11-coupled receptors.
TLDR
The results demonstrate that the internalization of mGluR1a is PKC/CaMKII-, GRK2-, arrestin-, and clathrin-dependent and that PKC- and CaMKII activation appears to be necessary forGRK2 to associate with mGlamorganically-coupled receptor 1, and that the heterologous desensitization of the splice variant is dependent upon the splices being in an active conformation.
Molecular Determinants of Metabotropic Glutamate Receptor 1B Trafficking
TLDR
The results indicate that these splice variants of mGluR1 utilize different targeting pathways and suggest that this may be a general phenomenon in the metabotropic glutamate receptor gene family.
