The following text describes a protein:
Function:
Orphan adhesion G-protein coupled receptor (aGPCR) (By similarity). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of downstream effectors, such as adenylate cyclase (By similarity). ADGRG4 is coupled to G(s) G proteins and mediates activation of adenylate cyclase activity. May be act as sensor of mechanical forces.
Subcellular Localization:
Membrane; Multi-pass membrane protein.
Domain:
The Stachel sequence (also named stalk) in the C-terminal part of the extracellular domain (ECD) functions as a tethered agonist. In the inactivated receptor, the Stachel sequence (also named stalk) is embedded in the GAIN-B domain, where it adopts a beta-strand conformation. On activation, the Stachel moves into the 7 transmembrane region and adopts a twisted hook-shaped configuration that forms contacts within the receptor, leading to coupling of a G-alpha protein, which activates signaling.
