abstract：:Latent transforming growth factor-beta 1 binding protein (LTBP) is a constituent of the latent high molecular weight complex of TGF-beta 1 in human platelets. In the present communication, we show that LTBP binds Ca2+ in its free form as well as in the latent TGF-beta 1 complex. The binding of Ca2+ induces a structura...
