Other synonyms may include: SP-I, betagranin (N-terminal fragment of chromogranin A), catestatin, chromofungin, and betagranin (N-terminal fragment of chromogranin A). It is encoded by the CHGA gene to yield a protein 457 amino acids in length and 50.7 kDa in size. The protein is categorized into the Chromogranin/secretogranin protein family. Versions of Vasostatin are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
