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.

Required for normal developmental progression throughout all life stages (PubMed:18262516, PubMed:22466039). Specifically required for the molt stage during all larval transitions and morphogenesis (PubMed:18262516, PubMed:17267616, PubMed:22466039). Acts with heterochronic genes, including members of the let-7 family, to regulate larval stage to adult transition (PubMed:18262516, PubMed:28933985). Acts synergistically with acn-1 in let-7 regulated postembryonic cell division of hypodermal seam cells (PubMed:28933985). Acts in multiple pathways to influence daf-12 and daf-16 activity to in turn regulate physiological and reproductive processes such as body size and egg-laying (PubMed:22466039). May play a role in neurotransmission (PubMed:20862215).5 Publications

Larval lethality during the L1 stage, with the formation of vacuoles in syncytial hypoderm, organ morphology defects, and molting defects (PubMed:17267616, PubMed:20862215). RNAi-mediated knockdown results in a reduced body size, transparent appearance, sluggish movement and insensitivity to touch (PubMed:18262516, PubMed:20862215). Delayed development and a molting defect that begins at the L3 to L4 larval stage transition and continues through to transition from the L4 larval stage to the young adult stage (PubMed:20862215). Increased sensitivity to acetylcholine inhibition (PubMed:20862215). Increased pharyngeal pumping (PubMed:11896189). In a let-7 mutant background, partial suppression of the let-7 bursting vulva phenotype (PubMed:28933985). Double RNAi-mediated knockdown with acn-1 in a let-7 mutant background leads to complete suppression of the heterochronic seam cell defects (PubMed:28933985).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:iA0816858FDD48608
