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). Inhibits
CC       host transcription (By similarity). Forms a tetrameric complex with
CC       XPO1/CRM1 and the nuclear import receptor importin (By similarity).
CC       This complex blocks the central channel of host nuclear pores thereby
CC       inhibiting the receptor-mediated nuclear transport and thus the host
CC       mRNA and rRNA transcription (By similarity). The inhibition of
CC       transcription is linked to a cytopathic effect on the host cell (By
CC       similarity). {ECO:0000250|UniProtKB:P03315,
CC       ECO:0000250|UniProtKB:P03316, ECO:0000250|UniProtKB:P09592,
CC       ECO:0000250|UniProtKB:P27284, ECO:0000250|UniProtKB:P36329}.
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:P03316};
CC   -!- SUBUNIT: [Capsid protein]: Part of a tetrameric complex composed of
CC       host CRM1, host importin alpha/beta dimer and the viral capsid; this
CC       complex blocks the receptor-mediated transport through the nuclear pore
CC       (By similarity). Interacts with host phosphatase PPP1CA; this
CC       interaction dephosphorylates the capsid protein, which increases its
CC       ability to bind to the viral genome (By similarity). Interacts with
CC       host karyopherin KPNA4; this interaction allows the nuclear import of
CC       the viral capsid protein (By similarity). Interacts with spike
CC       glycoprotein E2 (By similarity). Interacts with host IRAK1; the
CC       interaction leads to inhibition of IRAK1-dependent signaling (By
CC       similarity). {ECO:0000250|UniProtKB:P03315,
CC       ECO:0000250|UniProtKB:P03316, ECO:0000250|UniProtKB:P09592,
CC       ECO:0000250|UniProtKB:Q8JUX5}.
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   -!- 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   -!- 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). {ECO:0000250|UniProtKB:P03315,

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   -!- DOMAIN: [Capsid protein]: The very N-terminus plays a role in the
CC       particle assembly process (By similarity). The N-terminus also contains
CC       a nuclear localization signal and a supraphysiological nuclear export
CC       signal (supraNES), which is an unusually strong NES that mediates host
CC       CRM1 binding in the absence of RanGTP and thus can bind CRM1, not only
CC       in the nucleus, but also in the cytoplasm (By similarity). The C-
CC       terminus functions as a protease during translation to cleave itself
CC       from the translating structural polyprotein (By similarity).
CC       {ECO:0000250|UniProtKB:P03316, ECO:0000250|UniProtKB:P09592}.
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. The remaining polyprotein is then targeted to the
CC       host endoplasmic reticulum, where host signal peptidase cleaves it into
CC       pE2, 6K and E1 proteins. pE2 is further processed to mature E3 and E2
CC       by host furin in trans-Golgi vesicle. {ECO:0000250|UniProtKB:P03315}.
CC   -!- PTM: [Capsid protein]: Phosphorylated on serine and threonine residues.
CC       {ECO:0000250|UniProtKB:P09592}.
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   -!- PTM: [Spike glycoprotein E1]: N-glycosylated.
CC       {ECO:0000250|UniProtKB:P03315}.

CC       synthesized during togavirus replication.
