GPR126 is an adhesion G-protein coupled receptor; the second largest subgroup of GPCRs1. The defining characteristic of the adhesion GPCR family is their extraordinarily large N-terminal extracellular domain important to communicate with extracellular ligands and mediate adhesive functions2.
GPR126 is implicated in an increasing number of developmental defects: skeletal defects, including shortened height, adolescent idiopathic scoliosis, arthrogryposis multiplex congenital, and periodontitis. Other studies reveal that GPR126 is essential for myelination of axons in the peripheral nervous system and the heart2.
Known ligands of GPCR126 are type IV collagen (COLIV) in peripheral nerves and inner ear development, Laminin-211 during Schwann cell development, and prion protein in myelination3, suggesting that GPR126 could use different signaling pathways in different tissues4.
