The gene NPAS4 (neuronal PAS domain protein 4) is mapped to human chromosome 11q13. It is also referred to as NXF (neuronal transcription factor) and LE-PAS (limbic-enriched PAS domain protein). The encoded protein belongs to the basic helix-loop-helix (bHLH)-PAS (Per-ARNT-Sim) protein family. NPAS4 is mainly expressed in the brain and low levels are also present in the testis. The protein is present in the nucleus.NPAS4 protein interacts with:
•ARNT (anti-ARNT HPA001759)
•ARNTL (anti-ARNTL SAB4300614)
•ARNT2 (anti-ARNT2 HPA001056)
Synonyms: Anti-BHLHe79; Anti-Le-PAS; Anti-NXF; Anti-Neuronal PAS domain protein 4; Anti-PASD10

Biochem Physiol Actions: NPAS4 (neuronal PAS domain protein 4) is an activity-related transcription factor. It controls inhibitory and excitatory synapse formation. This action of NPAS4 depends on the neuronal cell type. NPAS4 also regulates the expression of brain-derived neurotrophic factor (BDNF), a neurotrophin required for neuronal viability, differentiation and synaptic plasticity. NPAS4 is associated with cognitive and social neurobehavior. In addition, it is involved in hippocampus- and amygdala-linked learning and memory. NPAS4 is also linked with psychiatric disorders, including bipolar disorder, autism spectrum disorder and cognition-associated disorders. This gene is also expressed during ischemic stroke and protects neurons against neurodegenerative insults.
