Osteogenic protein-1 (OP-1) expression and processing in Chinese hamster ovary cells: isolation of a soluble complex containing the mature and pro-domains of OP-1.


We have characterized the expression and processing of Osteogenic Protein-1 (hOP-1), a bone morphogenic protein of the TGF-beta family, in Chinese hamster ovary cells. The hOP-1 is initially synthesized as a monomeric 50 kDa pro-protein that is dimerized, glycosylated, and then proteolytically cleaved at the Arg-Xaa-Xaa-Arg maturation site in an acidic… (More)
