[5][6][7] The protein expressed by this gene is widely distributed in neuroendocrine tissues.

It functions as a chaperone protein for the proprotein convertase PC2 by blocking the aggregation of this protein, and is required for the production of an active PC2 enzyme.

[8][9] It is an intrinsically disordered protein that may also function as a chaperone for other aggregating secretory proteins in addition to proPC2 (Helwig et al. 2013).

7B2 has been identified in vertebrates and in invertebrates as low as flatworms (Protein ID: AIZ72728.1) and insects.
