Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Regulatory subunit of the histone acetylase B (HAT-B) complex (By similarity).

The complex acetylates 'Lys-12' of histone H4 which is required for telomeric silencing (By similarity).

Component of the CENP-A recruiting complex that ensures the integrity of mitotic spindles through maintenance of kinetochore factors mis6/CENP-I and cnp1/CENP-A (PubMed:15369671, PubMed:24774534, PubMed:24789708, PubMed:25375240).

Maintains the deacetylated state of histones specifically in the central core of the centromeres (PubMed:15369671).

<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:i606A7D009E60EA20
