Membrane receptor protein

A stylized membrane-bound receptor shown embedded vertically in a thin lipid bilayer. It has a larger extracellular folded globular binding domain with a distinct ligand-binding pocket or docking notch, a narrower membrane-spanning region consisting of a stem or one to several transmembrane segments crossing the membrane, and a small rounded intracellular signaling tail extending below the bilayer. The overall form is compact, clean, and schematic with smooth lobed surfaces, colored in blue, teal, or purple, with contrasting tones emphasizing the binding site.
