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>

Transcription factor essential for the identity of ASE chemosensory neurons. Acts by activating expression of genes that are specific for ASE chemosensory neurons, such as seven-transmembrane receptors or guanylate cyclase. Also required to control the left/right asymmetry in ASE chemosensory neurons by regulating expression of genes such as cog-1 and ceh-36.2 Publications
