Implicated in neuroendocrine secretory processes. May be involved in processes specific for neurosecretory granules, such as their biogenesis, trafficking or regulated exocytosis or may have a general role in neuroendocrine functions. Seems to lack intrinsic enzyme activity. May play a role in the regulation of secretory granules via its interaction with SNTB2. Interacts with phosphorylated SNTB2, protecting it from protein cleavage by CAPN1. Dephosphorylation of SNTB2 upon insulin stimulation disrupts the interaction and results in its cleavage.
