Protein
Secretogranin-1
Gene
CHGB
Organism
Bos taurus (Bovine)
Status
Functioni
Secretogranin-1 is a neuroendocrine secretory granule protein, which may be the precursor for other biologically active peptides. The 16 pairs of basic AA distributed throughout its sequence may be used as proteolytic cleavage sites.
Secretolytin has antibacterial activity.

Subcellular locationi
Other locations
Note: Neuroendocrine and endocrine secretory granules. Found to be membrane bound inside the secretory vesicles. The N-terminal region exhibits pH-dependent membrane-binding activity, binds to the membrane at intravesicular pH (5.5) and freed when the pH is near to physiological pH.
