Thrombospondin-1: Proteome Profiler Antibody Arrays

Thrombospondin-1 (TSP-1) is a secreted homotrimeric protein that regulates a wide range of cellular functions including their interactions with other cells and with the extracellular matrix (ECM). TSP-1 counteracts the angiogenic, hypotensive, and anti-thrombotic effects of nitric oxide (NO). It binds and neutralizes VEGF, blocks VEGF R2 signaling on vascular endothelial cells (EC), and destabilizes adhesive contacts between EC. TSP-1 also plays an important role in wound repair and tissue ...
