CC -!- FUNCTION: [Spike protein S1]: attaches the virion to the cell membrane
CC by interacting with host receptor, initiating the infection. Binding to
CC human ACE2 receptor and internalization of the virus into the endosomes
CC of the host cell induces conformational changes in the Spike
CC glycoprotein (PubMed:32142651, PubMed:32075877, PubMed:32155444). The
CC stalk domain of S contains three hinges, giving the head unexpected
CC orientational freedom (PubMed:32817270). Uses human TMPRSS2 for priming
CC in human lung cells which is an essential step for viral entry
CC (PubMed:32142651). Can be alternatively processed by host furin
CC (PubMed:32362314). Proteolysis by cathepsin CTSL may unmask the fusion
CC peptide of S2 and activate membranes fusion within endosomes.
CC {ECO:0000255|HAMAP-Rule:MF_04099, ECO:0000269|PubMed:32075877,
CC ECO:0000269|PubMed:32142651, ECO:0000269|PubMed:32155444,
CC ECO:0000269|PubMed:32362314, ECO:0000269|PubMed:32817270}.
CC -!- FUNCTION: [Spike protein S2]: mediates fusion of the virion and
CC cellular membranes by acting as a class I viral fusion protein. Under
CC the current model, the protein has at least three conformational
CC states: pre-fusion native state, pre-hairpin intermediate state, and
CC post-fusion hairpin state. During viral and target cell membrane
CC fusion, the coiled coil regions (heptad repeats) assume a trimer-of-
CC hairpins structure, positioning the fusion peptide in close proximity
CC to the C-terminal region of the ectodomain. The formation of this
CC structure appears to drive apposition and subsequent fusion of viral
CC and target cell membranes. {ECO:0000255|HAMAP-Rule:MF_04099}.
CC -!- FUNCTION: [Spike protein S2']: Acts as a viral fusion peptide which is
CC unmasked following S2 cleavage occurring upon virus endocytosis.
CC {ECO:0000255|HAMAP-Rule:MF_04099}.
CC -!- FUNCTION: [Spike glycoprotein]: May down-regulate host tetherin (BST2)
CC by lysosomal degradation, thereby counteracting its antiviral activity.
CC {ECO:0000250|UniProtKB:P59594}.
CC -!- SUBUNIT: [Spike glycoprotein]: Homotrimer; each monomer consists of a
CC S1 and a S2 subunit (PubMed:32075877, PubMed:32155444,
CC PubMed:32245784). The resulting peplomers protrude from the virus
CC surface as spikes (By similarity). Interacts with ORF3a protein and
CC ORF7a protein. {ECO:0000255|HAMAP-Rule:MF_04099,
CC ECO:0000269|PubMed:32075877, ECO:0000269|PubMed:32155444,

CC -!- SUBUNIT: [Spike protein S1]: Binds to host ACE2.

CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000255|HAMAP-
CC Rule:MF_04099}; Single-pass type I membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_04099}. Host endoplasmic reticulum-Golgi intermediate
CC compartment membrane {ECO:0000255|HAMAP-Rule:MF_04099}; Single-pass
CC type I membrane protein {ECO:0000255|HAMAP-Rule:MF_04099}. Host cell
CC membrane {ECO:0000255|HAMAP-Rule:MF_04099}; Single-pass type I membrane
CC protein {ECO:0000255|HAMAP-Rule:MF_04099}. Note=Accumulates in the
CC endoplasmic reticulum-Golgi intermediate compartment, where it
CC participates in virus particle assembly. Colocalizes with S in the host
CC endoplasmic reticulum-Golgi intermediate compartment. Some S oligomers
CC are transported to the host plasma membrane, where they may mediate
CC cell-cell fusion. {ECO:0000255|HAMAP-Rule:MF_04099}.
CC -!- DOMAIN: The KxHxx motif seems to function as an ER retrieval and binds
CC COPI in vitro. {ECO:0000250|UniProtKB:P59594}.
CC -!- DOMAIN: Fusion peptide 1 (FP1) and fusion peptide 2 (FP2) function
CC cooperatively and have a membrane-ordering effect on lipid headgroups
CC and shallow hydrophobic regions of target bilayers. They are considered
CC as two domains of an extended, bipartite FP. The membrane-ordering
CC activity is calcium-dependent and also dependent on correct folding,
CC which is maintained by an internal disulfide bond in FP2.
CC {ECO:0000255|HAMAP-Rule:MF_04099}.
CC -!- PTM: The cytoplasmic Cys-rich domain is palmitoylated. Spike
CC glycoprotein is digested within host endosomes. {ECO:0000255|HAMAP-
CC Rule:MF_04099}.
CC -!- PTM: Specific enzymatic cleavages in vivo yield mature proteins. The
CC precursor is processed into S1 and S2 by host cell furin or another
CC cellular protease to yield the mature S1 and S2 proteins
CC (PubMed:32155444). Additionally, a second cleavage leads to the release
CC of a fusion peptide after viral attachment to host cell receptor (By
CC similarity). The presence of a furin polybasic cleavage site sets SARS-
CC CoV-2 S apart from SARS-CoV S that possesses a monobasic S1/S2 cleavage
CC site processed upon entry of target cells (PubMed:32155444,
CC PubMed:32362314). {ECO:0000255|HAMAP-Rule:MF_04099,
CC ECO:0000269|PubMed:32155444, ECO:0000269|PubMed:32362314}.
CC -!- PTM: Highly decorated by heterogeneous N-linked glycans protruding from
CC the trimer surface (PubMed:32075877, PubMed:32155444). Highly
CC glycosylated by host both on S1 and S2 subunits, occluding many regions
CC across the surface of the protein. This may shield viral epitopes from
CC acquired immune response (PubMed:32366695, PubMed:32363391).
CC {ECO:0000269|PubMed:32075877, ECO:0000269|PubMed:32155444,
CC ECO:0000269|PubMed:32363391, ECO:0000269|PubMed:32366695}.
CC -!- SIMILARITY: Belongs to the betacoronaviruses spike protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04099}.
CC -!- CAUTION: Asn-17, Asn-603, Asn-1134, Asn-1158, and Asn-1173 are non
CC glycosylated when S1 or S2 are expressed individually in HEK293 cells.
CC {ECO:0000269|PubMed:32363391}.
