Product Detail	Function: 1 attaches the virion to the cell membrane by interacting with human ACE2 and CLEC4M/DC-SIGNR, initiating the infection. Binding to the receptor and internalization of the virus into the endosomes of the host cell probably induces conformational changes in the S glycoprotein. Proteolysis by cathepsin CTSL may unmask the fusion peptide of S2 and activate membranes fusion within endosomes. S2 is a class I viral fusion protein. Under the current model, the protein has at least three conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state. During viral and target cell membrane fusion, the coiled coil regions (heptad repeats) assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain. The formation of this structure appears to drive apposition and subsequent fusion of viral and target cell membranes. Subunit: Homotrimer. Binds to human and palm civet ACE2 and human CLEC4M/DC-SIGNR. Interacts with the accessory proteins 3a and 7a. {ECO:0000269|PubMed:14647384, ECO:0000269|PubMed:14670965, ECO:0000269|PubMed:15194747, ECO:0000269|PubMed:15496474, ECO:0000269|PubMed:16166518, ECO:0000269|PubMed:16840309}. Subcellular Location: Virion membrane {ECO:0000269|PubMed:15831954}; Single-pass type I membrane protein {ECO:0000269|PubMed:15831954}. Host endoplasmic reticulum-Golgi intermediate compartment membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Host cell membrane {ECO:0000269|PubMed:15831954}; Single-pass type I membrane protein {ECO:0000269|PubMed:15831954}. Note=Accumulates in the endoplasmic reticulum-Golgi intermediate compartment, where it participates in virus particle assembly (By similarity). Some S oligomers are transported to the plasma membrane, where they may mediate cell-cell fusion. {ECO:0000250}. Post-translational modifications: he cytoplasmic Cys-rich domain is palmitoylated. Spike glycoprotein is digested by cathepsin CTSL within endosomes. {ECO:0000269|PubMed:17134730}. Similarity: Belongs to the coronaviruses spike protein family. {ECO:0000305}.
