Disease
TSP2_HUMAN Genetic variations in THBS2 may be a cause of susceptibility to intervertebral disk disease (IDD) [MIM:603932; also known as lumbar disk herniation (LDH). IDD is one of the most common musculo-skeletal disorders and the predominant cause of low-back pain and unilateral leg pain.[1]
Function
TSP2_HUMAN Adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. Ligand for CD36 mediating antiangiogenic properties.[2]

Publication Abstract from PubMed
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.
