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 LDLRAD3. Synthesized
CC as a p62 precursor which is processed by furin at the cell membrane
CC just before virion budding, giving rise to E2-E1 heterodimer. The p62-
CC E1 heterodimer is stable, whereas E2-E1 is unstable and dissociate at
CC low pH. p62 is processed at the last step, presumably to avoid E1
CC fusion activation before its final export to cell surface. E2 C-
CC terminus 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 cell receptor LDLRAD3 and
CC endocytosis, acidification of the endosome would induce dissociation of
CC E1/E2 heterodimer and concomitant trimerization of the E1 subunits.
CC This E1 trimer is fusion active, and promotes release of viral
CC nucleocapsid in cytoplasm after endosome and viral membrane fusion.
CC Efficient fusion requires the presence of cholesterol and sphingolipid
CC in the target membrane. Fusion is optimal at levels of about 1 molecule
CC of 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 -!- SUBUNIT: [Precursor of protein E3/E2]: The precursor of protein E3/E2
CC and E1 form a heterodimer shortly after synthesis.

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). Interacts with host LDLRAD3; this interaction
CC mediates viral entry to the host cell (By similarity).

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}.
