Required for cig2 degradation in the G2 and M phases of the cell cycle. Together with pof6, essential for septum processing and cell separation. Involved in mitotic progression, essential for the execution of anaphase B; required for coordinated structural alterations of mitotic spindles and segregation of nuclear membrane structures at anaphase. Involved in the DNA damage checkpoint pathway and maintenance of genome integrity. Component of the RAVE complex which is required for stable assembly of the vacuolar ATPase complex V-ATPase.5 Publications

<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:i07EA1E97A3556E78
