open-in-new
<p>NPAS3 or Neuronal PAS domain protein 3 is a brain-enriched <a href="/facts/Transcription_factor/wro0DPHe">transcription factor</a> belonging to the <a href="/facts/Basic_helix-loop-helix/yqfuWejn">bHLH-PAS superfamily of transcription factors</a>, the members of which carry out diverse functions, including <a href="/facts/Circadian_oscillations/rwQh0ClJ">circadian oscillations</a>, <a href="/facts/Neurogenesis/XSteTv8s">neurogenesis</a>, <a href="/facts/Toxin/11oUNk7n">toxin</a> <a href="/facts/Metabolism/WxDrm8k5">metabolism</a>, <a href="/facts/Hypoxia_(medical)/JWV04G89">hypoxia</a>, and <a href="/facts/Vertebrate_trachea/zMSEwjAy">tracheal</a> development. NPAS3 contains <a href="/facts/Basic_helix-loop-helix/yqfuWejn">basic helix-loop-helix</a> structural motif and <a href="/facts/PAS_domain/LQoXUkWv">PAS domain</a>, like the other proteins in the superfamily. </p>
