Background Information

Chromogranin B is also named as Secretogranin-1, SgI, CgB, CHGB and SCG1. CHGB, a secretory granule protein, inserts itself into membrane and forms a chloride-conducting channel (PMID: 30456382). Native CHGB distributes nearly equally in soluble and membrane-bound forms, and both reconstitute highly selective anion channels in membrane (PMID: 37435575). The calculated molecular weight of Chromogranin B is at 78kDa. It has been shown that CHGB has a clear degradation band at ~50 kDa (https://www.biorxiv.org/content/10.1101/2019.12.28.890053v1.full.pdf).
