Neuronal PAS domain-containing protein 2 is a protein that in humans is encoded by the NPAS2 gene.[1][2]

Function[edit]

The protein encoded by this gene is a member of the basic helix-loop-helix (bHLH)-PAS family of transcription factors. A similar mouse protein may play a regulatory role in the acquisition of specific types of memory. It also may function as a part of a molecular clock operative in the mammalian forebrain.[3]

NPAS2 has been shown to be analogous to the function of CLOCK in CLOCK deficient mice.[4]

Interactions[edit]

NPAS2 has been shown to interact with:
