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>

Catalyzes the production of 7-dehydrocholesterol (7-DHC or cholesta-5,7-dien-3beta-ol) by inserting a double bond (desaturating) at the C7-C8 single bond of cholesterol (PubMed:21632547).

Essential regulator of steroid biosynthesis, as this reaction is the first step in the synthesis of the steroid hormone Delta7-dafachronic acid (PubMed:21632547, PubMed:16763204).

Required for insect molting, metamorphosis and body growth throughout development via the regulation of ecdysteroid biosynthesis in the prothoracic gland (PubMed:16763204).

Nvd_Dm plays a pivotal role in larval development in Drosophila. On this basis of the prolonged first instar larval phenotype, the gene was named 'neverland', which is the fictional island featured in J. M. Barrie's play Peter Pan, where children cease to age.1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence.
