An ectodomain is the domain of a membrane protein that extends into the extracellular space (the space outside a cell). Ectodomains are usually the part of a protein that initiate contact with surface which leads to signal transduction. In SARS-CoV the ectodomain of the spike protein is responsible for attachment to and entry into cells during infection.
