GPR56 is a a cell-surface G protein-coupled receptor (GPCR) which belongs to the adhesion G protein-coupled receptor (aGPCR) family, a large family of chimeric proteins that have both adhesion and signaling functions and play critical roles in diverse neurobiological processes including brain development, synaptogenesis, and myelination. This entry represents GPCR-Autoproteolysis-INducing (GAIN) subdomain A, including PLL-GAIN linker (F161-D175) region [1].

Adhesion G protein-coupled receptors (aGPCRs) play critical roles in diverse neurobiological processes including brain development, synaptogenesis, and myelination. The aGPCR GPR56/ADGRG1 regulates both oligodendrocyte and cortical development. The N-terminal domain of GPR56 has low sequence identity and a fold that likely diverged from the PTX and LNS domains. It also has a conserved motif (HphiC91xxWxxxxG) that was identified among canonical PTX domains. Thus, it is termed the Pentraxin/Laminin/neurexin/sex-hormone-binding-globulin-Like (PLL) domain. Truncation-based analyses suggest that the regions of GPR56 responsible for binding TG2 and collagen III are within the PLL domain, most likely in the surface-exposed conserved patch. Furthermore, it is suggested that the conserved patch of the PLL domain mediates an essential function in CNS myelination [1].
