Table 1 Names, loci, and molecular masses of granin proteins[1,2]

Name	Synonym	Locus	Number of amino acids and calculated molecular mass (kDa)
Chromogranin A	Parathyroid secretory protein 1	14q32.12	439 (49 kDa)
Chromogranin B	Secretogranin I	20pter-p12	657 (77 kDa)
Secretogranin II	Chromogranin C	2q35-q36	587 (68 kDa)
Secretogranin III	–	15q21	449 (51 kDa)
HISL-191	Secretogranin IV	–	–
7B2	Secretogranin V	15q13-q14	186 (21 kDa)
NESP55	Secretogranin VI	20q13.2	201 (23 kDa)
