CC -!- FUNCTION: [Capsid protein]: Forms an icosahedral capsid with a T=4
CC symmetry composed of 240 copies of the capsid protein surrounded by a
CC lipid membrane through which penetrate 80 spikes composed of trimers of
CC E1-E2 heterodimers (By similarity). The capsid protein binds to the
CC viral RNA genome at a site adjacent to a ribosome binding site for
CC viral genome translation following genome release (By similarity).
CC Possesses a protease activity that results in its autocatalytic
CC cleavage from the nascent structural protein (By similarity). Following
CC its self-cleavage, the capsid protein transiently associates with
CC ribosomes, and within several minutes the protein binds to viral RNA
CC and rapidly assembles into icosahedric core particles (By similarity).
CC The resulting nucleocapsid eventually associates with the cytoplasmic
CC domain of the spike glycoprotein E2 at the cell membrane, leading to
CC budding and formation of mature virions (By similarity). In case of
CC infection, new virions attach to target cells and after clathrin-
CC mediated endocytosis their membrane fuses with the host endosomal
CC membrane (By similarity). This leads to the release of the nucleocapsid
CC into the cytoplasm, followed by an uncoating event necessary for the
CC genomic RNA to become accessible (By similarity). The uncoating might
CC be triggered by the interaction of capsid proteins with ribosomes (By
CC similarity). Binding of ribosomes would release the genomic RNA since
CC the same region is genomic RNA-binding and ribosome-binding (By
CC similarity). Specifically inhibits interleukin-1 receptor-associated
CC kinase 1/IRAK1-dependent signaling during viral entry, representing a
CC means by which the alphaviruses may evade innate immune detection and
CC activation prior to viral gene expression (By similarity).
CC {ECO:0000250|UniProtKB:P03315, ECO:0000250|UniProtKB:P03316,
CC ECO:0000250|UniProtKB:P27284}.
CC -!- FUNCTION: [Assembly protein E3]: Provides the signal sequence for the
CC translocation of the precursor of protein E3/E2 to the host endoplasmic
CC reticulum. Furin-cleaved E3 remains associated with spike glycoprotein
CC E1 and mediates pH protection of the latter during the transport via
CC the secretory pathway. After virion release from the host cell, the
CC assembly protein E3 is gradually released in the extracellular space.
CC {ECO:0000250|UniProtKB:P03315}.
CC -!- FUNCTION: [Spike glycoprotein E2]: Plays a role in viral attachment to
CC target host cell, by binding to the cell receptor. Synthesized as a p62
CC precursor which is processed by furin at the cell membrane just before
CC virion budding, giving rise to E2-E1 heterodimer. The p62-E1
CC heterodimer is stable, whereas E2-E1 is unstable and dissociate at low
CC pH. p62 is processed at the last step, presumably to avoid E1 fusion
CC activation before its final export to cell surface. E2 C-terminus
CC contains a transitory transmembrane that would be disrupted by
CC palmitoylation, resulting in reorientation of the C-terminal tail from
CC lumenal to cytoplasmic side. This step is critical since E2 C-terminus
CC is involved in budding by interacting with capsid proteins. This
CC release of E2 C-terminus in cytoplasm occurs lately in protein export,
CC and precludes premature assembly of particles at the endoplasmic
CC reticulum membrane. {ECO:0000250|UniProtKB:P03315}.
CC -!- FUNCTION: [6K protein]: Constitutive membrane protein involved in virus
CC glycoprotein processing, cell permeabilization, and the budding of
CC viral particles. Disrupts the calcium homeostasis of the cell, probably
CC at the endoplasmic reticulum level. This leads to cytoplasmic calcium
CC elevation. Because of its lipophilic properties, the 6K protein is
CC postulated to influence the selection of lipids that interact with the
CC transmembrane domains of the glycoproteins, which, in turn, affects the
CC deformability of the bilayer required for the extreme curvature that
CC occurs as budding proceeds. Present in low amount in virions, about 3%
CC compared to viral glycoproteins. {ECO:0000250|UniProtKB:P03315}.
CC -!- FUNCTION: [Spike glycoprotein E1]: Class II viral fusion protein.
CC Fusion activity is inactive as long as E1 is bound to E2 in mature
CC virion. After virus attachment to target cell and endocytosis,
CC acidification of the endosome would induce dissociation of E1/E2
CC heterodimer and concomitant trimerization of the E1 subunits. This E1
CC trimer is fusion active, and promotes release of viral nucleocapsid in
CC cytoplasm after endosome and viral membrane fusion. Efficient fusion
CC requires the presence of cholesterol and sphingolipid in the target
CC membrane. Fusion is optimal at levels of about 1 molecule of
CC cholesterol per 2 molecules of phospholipids, and is specific for
CC sterols containing a 3-beta-hydroxyl group.
CC {ECO:0000250|UniProtKB:P03315}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Autocatalytic release of the core protein from the N-terminus
CC of the togavirus structural polyprotein by hydrolysis of a -Trp-|-
CC Ser- bond.; EC=3.4.21.90; Evidence={ECO:0000250|UniProtKB:P03315};
CC -!- SUBUNIT: [Capsid protein]: Homodimer (By similarity). Homomultimer
CC (Probable). Interacts with host karyopherin KPNA4; this interaction
CC allows the nuclear import of the viral capsid protein (By similarity).
CC Interacts with spike glycoprotein E2 (By similarity). Interacts with
CC host IRAK1; the interaction leads to inhibition of IRAK1-dependent
CC signaling (By similarity). {ECO:0000250|UniProtKB:P03315,
CC ECO:0000250|UniProtKB:P03316, ECO:0000250|UniProtKB:P0DOK1,
CC ECO:0000250|UniProtKB:Q8JUX5, ECO:0000305}.
CC -!- SUBUNIT: [Precursor of protein E3/E2]: The precursor of protein E3/E2
CC and E1 form a heterodimer shortly after synthesis (By similarity).
CC {ECO:0000250|UniProtKB:P03315, ECO:0000250|UniProtKB:P03316,
CC ECO:0000250|UniProtKB:P0DOK1, ECO:0000250|UniProtKB:Q8JUX5}.
CC -!- SUBUNIT: [Spike glycoprotein E1]: The precursor of protein E3/E2 and E1
CC form a heterodimer shortly after synthesis (By similarity). Processing
CC of the precursor of protein E3/E2 into E2 and E3 results in a
CC heterodimer of the spike glycoproteins E2 and E1 (By similarity). Spike
CC at virion surface are constituted of three E2-E1 heterodimers (By
CC similarity). After target cell attachment and endocytosis, E1 change
CC conformation to form homotrimers (By similarity). Interacts with 6K
CC protein (By similarity). {ECO:0000250|UniProtKB:P03315,
CC ECO:0000250|UniProtKB:P03316, ECO:0000250|UniProtKB:P0DOK1,

CC -!- SUBUNIT: [Spike glycoprotein E2]: Processing of the precursor of
CC protein E3/E2 into E2 and E3 results in a heterodimer of the spike
CC glycoproteins E2 and E1 (By similarity). Spike at virion surface are
CC constituted of three E2-E1 heterodimers (By similarity). Interacts with
CC 6K protein (By similarity). Interacts with host MXRA8; this interaction
CC mediates virus entry (By similarity). {ECO:0000250|UniProtKB:P03315,

CC -!- DOMAIN: [Capsid protein]: The very N-terminus also plays a role in the
CC particle assembly process (By similarity). The N-terminus also contains
CC a nuclear localization signal and a supra nuclear export signal
CC (supraNES), which is an unusually strong NES that mediates host CRM1
CC binding in the absence of RanGTP and thus can bind CRM1, not only in
CC the nucleus, but also in the cytoplasm (By similarity). The C-terminus
CC functions as a protease during translation to cleave itself from the
CC translating structural polyprotein (By similarity).
CC {ECO:0000250|UniProtKB:P03316, ECO:0000250|UniProtKB:P09592}.
CC -!- DOMAIN: Structural polyprotein: As soon as the capsid protein has been
CC autocleaved, an internal uncleaved signal peptide directs the remaining
CC polyprotein to the endoplasmic reticulum.
CC {ECO:0000250|UniProtKB:P03315}.
CC -!- PTM: Structural polyprotein: Specific enzymatic cleavages in vivo yield
CC mature proteins. Capsid protein is auto-cleaved during polyprotein
CC translation, unmasking a signal peptide at the N-terminus of the
CC precursor of E3/E2 (By similarity). The remaining polyprotein is then
CC targeted to the host endoplasmic reticulum, where host signal peptidase
CC cleaves it into pE2, 6K and E1 proteins. pE2 is further processed to
CC mature E3 and E2 by host furin in trans-Golgi vesicle (By similarity).
CC {ECO:0000250|UniProtKB:P03315}.
CC -!- PTM: [Spike glycoprotein E2]: Palmitoylated via thioester bonds. These
CC palmitoylations may induce disruption of the C-terminus transmembrane.
CC This would result in the reorientation of E2 C-terminus from lumenal to
CC cytoplasmic side. {ECO:0000250|UniProtKB:P03315}.

CC {ECO:0000250|UniProtKB:P03315}.
CC -!- MISCELLANEOUS: Structural polyprotein: Translated from a subgenomic RNA
CC synthesized during togavirus replication.
