RNAi-mediated knockdown is lethal at larval stage (PubMed:25164807). RNAi-mediated knockdown in the developing CNS, in the eye and antenna disk from early larval stages shows increased lifespan with reduction of COX activity, increased succinate dehydrogenase (SDH) activity, reduced locomotor speed and response to light (PubMed:16172499, PubMed:25164807). RNAi-mediated knockdown in mesodermal derivatives from early embryonic stages to pupal metamorphosis is lethal at pupal stage with muscles showing enlarged and disorganized mitochondria and reduced activity of all mitochondrial respiratory chain complexes (PubMed:25164807).2 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:i59C6969FA0E9A9C1
