Neuronal PAS domain-containing protein 1 (NPAS1)

May control regulatory pathways relevant to schizophrenia and to psychotic illness. May play a role in late central nervous system development by regulating EPO expression in response to cellular oxygen level (By similarity).

Forms a heterodimer that binds core DNA sequence 5'-TACGTG-3' inside the hypoxia response element (HRE) resulting in transcriptional repression on its target receptor TH (By similarity). .
