Capsid protein VP1: Capsid proteins VP1, VP2, and VP3 form a closed capsid enclosing the viral positive strand RNA genome. All these proteins contain a beta-sheet structure called beta-barrel jelly roll. Together they form an icosahedral capsid (T=3) composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes. The naked capsid interacts with the host receptor HAVCR1 to provide virion attachment to and probably entry into the target cell.By similarity
Capsid protein VP2: Capsid proteins VP1, VP2, and VP3 form a closed capsid enclosing the viral positive strand RNA genome. All these proteins contain a beta-sheet structure called beta-barrel jelly roll. Together they form an icosahedral capsid (T=3) composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes. The naked capsid interacts with the host receptor HAVCR1 to provide virion attachment to and probably entry into the target cell.By similarity
Capsid protein VP3: Capsid proteins VP1, VP2, and VP3 form a closed capsid enclosing the viral positive strand RNA genome. All these proteins contain a beta-sheet structure called beta-barrel jelly roll. Together they form an icosahedral capsid (T=3) composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes. The naked capsid interacts with the host receptor HAVCR1 to provide virion attachment to and probably entry into the target cell.By similarity
Protein VP0: VP0 precursor is a component of the immature procapsids.By similarity
Protein VP4: Plays a role in the assembly of the 12 pentamers into an icosahedral structure. Has not been detected in mature virions, supposedly owing to its small size.By similarity
Protein VP1-2A: Precursor component of immature procapsids that corresponds to an extended form of the structural protein VP1. After maturation, possibly by the host Cathepsin L, the assembly signal 2A is cleaved to give rise to the mature VP1 protein.By similarity
Protein 2B: Function as a viroporin. Affects membrane integrity and causes an increase in membrane permeability. Involved in host intracellular membrane rearrangements probably to give rise to the viral factories. Does not disrupt calcium homeostasis or glycoprotein trafficking. Antagonizes the innate immune response of the host by suppressing IFN-beta synthesis, which it achieves by interfering with the DDX58/IFIH1 (RIG-I/MDA5) pathway.By similarity
Protein 2BC: Affects membrane integrity and causes an increase in membrane permeability.By similarity
Protein 2C: Associates with and induces structural rearrangements of intracellular membranes. Displays RNA-binding activity.By similarity
Protein 3ABC: The precursor 3ABC is targeted to the mitochondrial membrane where protease 3C activity cleaves and inhibits the host antiviral protein MAVS, thereby disrupting activation of IRF3 through the IFIH1/MDA5 pathway. In vivo, the protease activity of 3ABC precursor is more efficient in cleaving the 2BC precursor than that of protein 3C. The 3ABC precursor may therefore play a role in the proteolytic processing of the polyprotein. Possible viroporin.By similarity
Protein 3AB: Interacts with the 3CD precursor and with RNA structures found at both the 5'- and 3'-termini of the viral genome. Since the 3AB precursor contains the hydrophobic domain 3A, it probably anchors the whole viral replicase complex to intracellular membranes on which viral RNA synthesis occurs.By similarity
Protein 3A: May serve as membrane anchor to the 3AB and 3ABC precursors via its hydrophobic domain. May interact with RNA.By similarity
Viral protein genome-linked: Acts as a primer for viral RNA replication and remains covalently bound to viral genomic RNA. VPg is uridylylated prior to priming replication into VPg-pUpU. The VPg-pUpU is then used as primer on the genomic RNA poly(A) by the RNA-dependent RNA polymerase to replicate the viral genome.By similarity
Protease 3C: Cysteine protease that generates mature viral proteins from the precursor polyprotein. In addition to its proteolytic activity, it binds to viral RNA, and thus influences viral genome replication. RNA and substrate bind cooperatively to the protease. Cleaves IKBKG/NEMO to impair innate immune signaling. Cleaves host PABPC1 which may participate to the switch of viral translation to RNA synthesis.By similarity
Protein 3CD: Interacts with the 3AB precursor and with RNA structures found at both the 5'- and 3'-termini of the viral genome. Disrupts TLR3 signaling by degrading the host adapter protein TICAM1/TRIF.By similarity
RNA-directed RNA polymerase 3D-POL replicates genomic and antigenomic RNA by recognizing replications specific signals.By similarity

Miscellaneous

Genome polyprotein: The need for an intact eIF4G factor for the initiation of translation of HAV results in an inability to shut off host protein synthesis by a mechanism similar to that of other picornaviruses.By similarity
Genome polyprotein: During infection, enveloped virions (eHAV) are released from cells. These eHAV are cloaked in host-derived membranes and resemble exosomes. The membrane of eHAV is devoid of viral proteins and thus prevents their neutralization by antibodies. eHAV budding is dependent on ESCRT-associated proteins VPS4B and PDCD6IP/ALIX. eHAV are produced and released in the serum and plasma, but not in bile and feces which only contain the naked, nonenveloped virions. It is likely that eHAV also use HAVCR1 as a functional receptor to infect cells, an evolutionary trait that may enhance HAV infectivity.By similarity

Genome polyprotein: Specific enzymatic cleavages by viral protease in vivo yield a variety of precursors and mature proteins. Polyprotein processing intermediates are produced, such as P1-2A which is a functional precursor of the structural proteins, VP0 which is a VP4-VP2 precursor, VP1-2A precursor, 3ABC precursor which is a stable and catalytically active precursor of 3A, 3B and 3C proteins, 3AB and 3CD precursors. The assembly signal 2A is removed from VP1-2A by a host protease, possibly host Cathepsin L. This cleavage occurs over a region of 3 amino-acids probably generating VP1 proteins with heterogeneous C-termini. During virion maturation, non-infectious particles are rendered infectious following cleavage of VP0. This maturation cleavage is followed by a conformational change of the particle.By similarity
Protein VP1-2A: The assembly signal 2A is removed from VP1-2A by a host protease, possibly host Cathepsin L in nacked virions. This cleavage does not occur in enveloped virions. This cleavage occurs over a region of 3 amino-acids probably generating VP1 proteins with heterogeneous C-termini.By similarity
Viral protein genome-linked: VPg is uridylylated prior to priming replication into VPg-pUpU.By similarity
Protein VP4: Unlike other picornaviruses, does not seem to be myristoylated.By similarity

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i87B3230E324E1F19
