Abstract

To investigate the processing of transforming growth factor β1 (TGFβ1) pro-protein by furin protease we expressed a GST-pro-TGFβ1 fusion protein in bacteria. Analysis of the furin digestion pattern revealed the liberation of 12.5 kDa TGFβ1 monomers. There was no evidence for cleavage of an alternative furin site within the pro-protein.

Keywords: Transforming growth factor β1, furin, proteolytic processing
