Leader cysteine autoprotease that cleaves itself from the nascent polyprotein during translation of the viral mRNA. Once released, plays a role in the inhibition of host innate immune response by interacting with host IRF3 and inducing its proteasomal degradation.

By similarity

Packages viral RNA to form a viral nucleocapsid and thereby protects viral RNA. Plays also a role in transcription regulation. Protects the incoming virus against IFN-induced effectors.

By similarity

Plays a role in viral entry. Interacts with host RPSA that acts as a cellular attachment receptor for the virus. Possesses also intrinsic ribonuclease (RNase) activity that can inhibit the production of type I interferon and assist in the development of persistent infections.

By similarity

Plays a role in cell attachment and subsequent fusion of viral and cellular membranes. Therefore, mediates together with envelope glycoprotein E2 the viral entry.

By similarity

Plays a role in cell attachment and subsequent fusion of viral and cellular membranes. Therefore, mediates together with envelope glycoprotein E1 the viral entry.

By similarity

Plays an essential role in the virus replication cycle by acting as a viroporin. Forms ion conductive pores, which alters the cell permeability allowing the transport of ions and other small molecules.

By similarity

Autoprotease that associates with the host chaperone JIV and cleaves the NS2-3 protein between NS2 and NS3. Plays also a role in the formation of infectious particles.

By similarity

Plays a role in the regulation of viral RNA replication.

By similarity

Multifunctional protein that contains an N-terminal protease and a C-terminal helicase, playing essential roles in viral polyprotein processing and viral genome replication. The chymotrypsin-like serine protease activity utilizes NS4A as an essential cofactor and catalyzes the cleavage of the polyprotein leading to the release of NS4A, NS4B, NS5A, and NS5B. Plays a role in the inhibition of host NF-kappa-B activation by interacting with and inhibiting host TRAF6. Interacts with NS5B to enhance RNA-dependent RNA polymerase activity.

By similarity

Acts as a cofactor for the NS3 protease activity.

By similarity

Induces a specific membrane alteration that serves as a scaffold for the virus replication complex (By similarity).

Antagonizes host cell apoptosis by interacting with host ferritin heavy chain. The ORF4 protein physically binds host FTH1/FHC, resulting in the reduction of FTH1 protein levels in host cells. Reduction of FTH1 concentration further inhibits the accumulation of reactive oxygen in host cells, leading to reduced apoptosis.

By similarity

Regulates viral RNA replication by interacting with the 3'-untranslated region of viral RNA in a dose-dependent manner. At small concentrations promotes viral synthesis by interacting with the polymerase NS5B while at large concentrations, inhibits replication.

By similarity

Replicates the viral (+) and (-) genome.

Heavily glycosylated.By similarity
The viral RNA of pestiviruses is expressed as a single polyprotein which undergoes post-translational proteolytic processing resulting in the production of at least eleven individual proteins. The N-terminal protease cleaves itself from the nascent polyprotein autocatalytically and thereby generates the N-terminus of the adjacent viral capsid protein C.By similarity
Cleavage between E2 and p7 is partial.

<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:iEC6EB207A09D59FD

<p>This subsection of the 'Entry information' section provides a mnemonic identifier for a UniProtKB entry, but it is not a stable identifier. Each reviewed entry is assigned a unique entry name upon integration into UniProtKB/Swiss-Prot.<p><a href='/help/entry_name' target='_top'>More...</a></p>Entry nameiPOLG_CSFVB
<p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P21530
<p>This subsection of the 'Entry information' section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification ('Last modified'). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical%5Fand%5Fisoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: May 1, 1991

This is version 159 of the entry and version 1 of the sequence. See complete history.
<p>This subsection of the 'Entry information' section indicates whether the entry has been manually annotated and reviewed by UniProtKB curators or not, in other words, if the entry belongs to the Swiss-Prot section of UniProtKB (<strong>reviewed</strong>) or to the computer-annotated TrEMBL section (<strong>unreviewed</strong>).<p><a href='/help/entry_status' target='_top'>More...</a></p>Entry statusiReviewed (UniProtKB/Swiss-Prot)
