Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

The different isoforms prevent the establishment of cellular antiviral state by blocking the interferon-alpha/beta (IFN-alpha/beta) and IFN-gamma signaling pathways. They inhibit IFN-alpha/beta induced tyrosine phosphorylation of STAT1 and STAT2. Blocking the IFN-alpha/beta pathway requires binding to STAT1 in the cytoplasm. They inhibit IFN-gamma induced serine phosphorylation of STAT1. Block the IFN-gamma pathway by binding to and stabilizing the parallel form of the STAT1 dimer, further inducing high-molecular-weight complex (HMWC) formation and inhibition of transcription by IFN-gamma. May also have a role in preventing the cell to enter apoptosis. Modulate regulation of viral transcription and replication. Overexpression inhibits the viral RNA polymerase. The absence of all C', C, Y1 and Y2 proteins leads to viral delayed growth. Plays an important role in virion particles release. Modulates virion shape.8 Publications

Miscellaneous

The P/V/C gene has two overlapping open reading frames. One encodes the P/V/W proteins and the other the C/Y proteins.Curated

Caution

The C' protein uses an unusual ACG start codon.Curated

The different isoforms interact (via C-terminus) with unphosphorylated and phosphorylated human STAT1 (via N-terminus), favoring the formation of parallel STAT1 homodimers (PubMed:11442634, PubMed:26339056). The different isoforms do not interact with host STAT2 (PubMed:11442634, PubMed:26339056). C protein interacts with L protein; this interaction has an inhibitory effect on viral transcription and replication (PubMed:9281506, PubMed:11543662).

<p>This subsection of the 'Family and domains' section provides general information on the biological role of a domain.

Several domains are described in this subsection.<p><a href='/help/domain_cc' target='_top'>More...</a></p>Domaini

The disordered region at the N-terminus is involved in C protein self-degradation in trans. This self-degradation of C protein may play a role in the regulation of viral RNA synthesis. The disordered region at the N-terminus is also involved in the host STAT1 degradation in order to counteract the host innate antiviral response.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.
