Vasorin is a Type I membrane protein, which is predominantly expressed in vascular smooth muscle cells in a developmentally regulated pattern. The expression level of Vasorin can be down regulated during vessel repair after arterial injury. Vasorin binds to transforming growth factor beta (TGF-beta) and attenuates TGF-beta signaling in vitro.Alternative Names: Vasorin, Protein Slit-Like 2, VASN, SLITL2
