Neuroendocrine protein 7B2 is a protein that in humans is encoded by the SCG5 gene.^[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 and is required for the production of an active PC2 enzyme.^[4][5]
