<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>

Structural component of the virion that acts as a cement protein on the capsid exterior and which mediates the interactions between the hexons, including the peripentonal hexons, and reaches all the way to the penton vertices. Two hexon linking proteins IIIa, one from each facet, stabilize the unique edge interface between a pair of facets. As the virus enters the host cell, hexon linking proteins IIIa are shed concomitant with virion acidification in the endosome. During virus assembly, seems to play a role in the serotype specificity of the packaging of viral DNA via its interaction with packaging protein 3.UniRule annotation3 Publications

Miscellaneous

All late proteins expressed from the major late promoter are produced by alternative splicing and alternative polyadenylation of the same gene giving rise to non-overlapping ORFs. A leader sequence is present in the N-terminus of all these mRNAs and is recognized by the viral shutoff protein to provide expression although conventional translation via ribosome scanning from the cap has been shut off in the host cell.UniRule annotation

Caution

An interaction between hexon-linking protein IIIa and hexon-linking protein VIII as been described in PubMed:20798312. However, the subcellular location of hexon-linking protein IIIa was incorrectly assigned to the capsid interior.Curated

<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.
