UniProtKB description: Binds to host cell surface receptor LDLR and mediates fusion between viral and cellular membranes. Attachment to receptor induces virion internalization predominantly through clathrin-dependent endocytosis. Class II fusion protein that promotes fusion of viral membrane with host endosomal membrane after endocytosis of the virion. Exposure of the glycoprotein spikes to potassium is necessary for the conformational change leading to fusion.
