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>The checksum is a form of redundancy check that is calculated from the sequence.

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 subsection of the ‘Sequence’ section provides information on polymorphic variants. If the variant is associated with a disease state, the description of the latter can be found in the <a href="http://www.uniprot.org/manual/involvement_in_disease">'Involvement in disease'</a> subsection.<p><a href='/help/polymorphism' target='_top'>More...</a></p>Polymorphismi

The following alleles of A-11 are known: A*11:01 (A-11E), A*11:02 (A-11K), A*11:03, A*11:04, A*11:05 and A*11:07. The sequence shown is that of A*11:01.
