Abstract excerpt
Transforming growth factor-beta1 (TGF-beta1) is secreted as part of an inactive complex consisting of the mature dimer, the TGF-beta1 propeptide (latency-associated peptide (LAP)), and latent TGF-beta-binding proteins. Using in vitro mutagenesis, we identified the regions of LAP that govern the cooperative assembly and stability of the latent TGF-beta1 complex. Initially, hydrophobic LAP residues (Ile(53),...
