The proprotein convertases (PCs) are a seven-member family of endoproteases that activate proproteins by cleavage at basic motifs. Expression patterns for individual PCs vary widely, and all cells express several members. The list of substrates activated by PCs has grown to include neuropeptides, peptide hormones, growth and differentiation factors,(More)
The protein designated 7B2 is a recently discovered pituitary polypep-tide which is selectively expressed in cells containing secretory granules, such as neurons and endocrine cells. Northern blot analysis of 7B2 gene expression in small cell lung carcinoma (SCLC) cell lines revealed that 7B2 was expressed in all nine cell lines of the classic type tested,(More)
