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>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Glycosyltransferase involved in the xylosylation of N-glycans (PubMed:10781814, PubMed:12943552, PubMed:15013764, PubMed:15686448).

Possesses beta-1,2-xylosyltransferase activity, transferring xylose from UDP-xylose to the core beta-linked mannose of N-glycans (PubMed:10781814, PubMed:12943552, PubMed:15013764, PubMed:15686448).

Involved in the biosynthesis of glycoprotein bound N-glycans (PubMed:15686448, PubMed:22024534).

Does not require metal ions for its activity (PubMed:15686448).

<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.
