STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Neuregulin 1 or NRG1 is one of four proteins in the neuregulin family that act on the EGFR family of receptors. Neuregulin 1 is produced in numerous isoforms by alternative splicing, which allows it to perform a wide variety of functions. It is essential for the normal development of the nervous system and the heart. Neuregulin 1-ErbB4 interactions are thought to play a role in the pathological mechanism of schizophrenia.  The NRG1-ErbB4 signaling complex has been highlighted as a potential target for new antipsychotic treatment. Neuregulin 1 has been shown to modulate anxiety-like behaviors.  Neuregulin has been shown to be involved in the myelination of central nervous system axon.  Diseases associated with NRG1 include schizophreniform disorder and schizophrenia.
