Chemokines, such as Stromal Derived Factor 1 (SDF-1 or CXCL12) and their G protein coupled receptors (GPCRs) are well known regulators of the development and functions of numerous tissues. CXCL12 has two receptors: CXCR4 and CXCR7 or atypical chemokine receptor 3 (ACKR3). CXCR7 has been described as an atypical “biased”...
In mature neurons, postsynaptic NMDARs are segregated into two populations, synaptic and extrasynaptic NMDARs, which differ in localization, function, and associated intracellular cascades. These two pools are connected via lateral diffusion, and receptor exchange between them modulates synaptic NMDAR content (NMDAR-plasticity). Here, we identify the phosphorylation of the PDZ-ligand of...
