G-protein coupled receptor which is activated by type IV collagen, a major constituent of the basement membrane (By similarity). Couples to G(i)-proteins as well as G(s)-proteins (PubMed:24227709). Essential for normal differentiation of promyelinating Schwann cells and for normal myelination of axons (PubMed:24227709). Regulates neural, cardiac and ear development via G-protein- and/or N-terminus-dependent signaling (By similarity). May act as a receptor for PRNP which may promote myelin homeostasis (By similarity). Interacts with Laminin-2; this interaction stabilizes the receptor in an inactive state. Laminin-2 polymerization could facilitate ADGRG6-NTF removal, thereby exposing the tethered agonist to drive myelination. Interacts with PRNP. Detected on the cell surface of activated but not resting umbilical vein. Expressed in placenta and to a lower extent in pancreas and liver. Detected in aortic endothelial cells but not in skin microvascular endothelial cells. Up-regulated by bacterial lipopolysaccharides (LPS) and thrombin, but not by other inflammatory stimuli in primary umbilical veins. A short peptide sequence (termed the Stachel sequence) in the C-terminal part of the extra-cellular domain (ECD) functions as a tethered agonist. Upon structural changes within the ECD, e.g. due to extracellular ligand binding or mechanical movements, this intramolecular agonist is exposed to the 7TM domain, triggering G-protein activation. Proteolytically cleaved into 2 conserved sites: one in the GPS domain (S1 site) and the other in the middle of the extracellular domain (S2 site). The proteolytic cleavage at S1 site generates an extracellular subunit and a seven-transmembrane subunit. Furin is involved in the cleavage of the S2 site generating a soluble fragment. Processing at the GPS domain occurred independent of and probably prior to the cleavage at the S2 site. Proteolytic cleavage is required for activation of the receptor. Highly glycosylated. Genetic variations in ADGRG6 influences stature as a quantitative trait (STQTL) [MIM:606255]. Adult height is an easily observable and highly heritable complex continuous trait. Because of this, it is a model trait for studying genetic influence on quantitative traits. The disease is caused by variants affecting the gene represented in this entry. Belongs to the G-protein coupled receptor 2 family. Adhesion G-protein coupled receptor (ADGR) subfamily. Sequencing errors. Truncated N-terminus. Truncated N-terminus. Extended N-terminus.
