Cell surface protein

A small cell-surface membrane protein depicted as a compact protruding receptor or surface marker emerging from the outer face of the plasma membrane. It has a short transmembrane or stalk-like base embedded in the membrane and a distinct extracellular domain that is rounded, bulb-like, globular, slightly elongated, forked, Y-shaped, lollipop-like, or subtly hook-shaped to suggest a binding or docking site. The protein is colored blue, teal, green, or purple, and may include small attached sugar branches indicating a glycoprotein. Suitable for cell-cell contact or receptor-binding diagrams.
