Conserved domain between CgA&CgB
one near the N-terminal region bordered by two cysteine residues (residues 17–38 in bovine CGA and 16–37 in bovine CGB) and the other the C-terminal region (residues 409–431 in bovine CGA and 604–626 in bovine CGB)
Disulfide bond loop가 membrane에 bind하고, secretory granule을 형성하는데 큰 역할을 한다.
- CgA와 CgB는 granule 형성의 on/off switch.
- The aggregation of CGB being at least two orders of magnitude more sensitive to Ca2 than CGA
- Unlike CGA, which dimerized at pH 7.5 and tetramerized at pH5.5 (21, 22), purified CGB appeared to exist in a monomeric state
