The protein encoded by this gene is a member of the
chromogranin/secretogranin family of neuroendocrine secretory proteins. Studies in rodents suggest that the full-length protein, secretogranin II, is involved in the packaging or sorting of
peptide hormones and
neuropeptides into secretory vesicles. The full-length protein is cleaved to produce the active peptide
secretoneurin, which exerts
chemotactic effects on specific cell types, and EM66, whose function is unknown. == See also ==
