Strucuture of the C-terminal domain of human thrombospondin-2
Overview
Thrombospondins (THBSs) are secreted glycoproteins that have key roles in interactions between cells and the extracellular matrix. Here, we describe the 2.6-A-resolution crystal structure of the glycosylated signature domain of human THBS2, which includes three epidermal growth factor-like modules, 13 aspartate-rich repeats and a lectin-like module. These elements interact extensively to form three structural regions termed the stalk, wire and globe. The THBS2 signature domain is stabilized by these interactions and by a network of 30 bound Ca(2+) ions and 18 disulfide bonds. The structure suggests how genetic alterations of THBSs result in disease.
