Neuroendocrine protein 7B2 is a protein that in humans is encoded by the SCG5gene.[1][2][3] 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.[4][5] It is an intrinsically disordered protein that may also function as a chaperone for other proteins in addition to proPC2.
