secretogranin ii lacks the disulfide-bonded loop structure near the nh2 terminus which is conserved in chromogranin a and chromogranin b ( secretogranin i ) , two other widespread constituents of neuroendocrine secretory granules , but like the latter two proteins contains ( i ) an -e-n/s-l-x-a/d-x-d/e-x-e-l- motif and ( ii ) multiple potential dibasic cleavage sites for the generation of smaller , perhaps biologically active peptides .
