FunctionAGRL3_MOUSE Plays a role in cell-cell adhesion and neuron guidance via its interactions with FLRT2 and FLRT3 that are expressed at the surface of adjacent cells (PubMed:22405201, PubMed:25728924, PubMed:26235031). Plays a role in the development of glutamatergic synapses in the cortex (PubMed:22405201, PubMed:24739570). Important in determining the connectivity rates between the principal neurons in the cortex (PubMed:24739570).[1] [2] [3] [4] Publication Abstract from PubMedLatrophilins (LPHNs) are adhesion-like G-protein-coupled receptors implicated in attention-deficit/hyperactivity disorder. Recently, LPHN3 was found to regulate excitatory synapse number through trans interactions with fibronectin leucine-rich repeat transmembrane 3 (FLRT3). By isothermal titration calorimetry, we determined that only the olfactomedin (OLF) domain of LPHN3 is necessary for FLRT3 association. By multi-crystal native single-wavelength anomalous diffraction phasing, we determined the crystal structure of the OLF domain. This structure is a five-bladed beta propeller with a Ca2+ ion bound in the central pore, which is capped by a mobile loop that allows the ion to exchange with the solvent. The crystal structure of the OLF/FLRT3 complex shows that LPHN3-OLF in the closed state binds with high affinity to the concave face of FLRT3-LRR with a combination of hydrophobic and charged residues. Our study provides structural and functional insights into the molecular mechanism underlying the contribution of LPHN3/FLRT3 to the development of glutamatergic synapses.
