Target Details

Target: GARP & Latent TGF beta 1 Complex

Background: GARP&Latent TGF Beta is a complex found on surface of many types of cells. In Tregs, GARP is involved in TCR-mediated activation of Latent TGF-β and thus promoting secretion and activation of TGF-β. Integrin αvβ8 on the surface of immune cells and other cells recognizes RGD in LAP, resulting in the release of mature TGF-β from the TGF-β&GARP complex.

Molecular Weight: 70.5 kDa (GARP)&41.3 kDa (Latent TGF Beta 1). Due to glycosylation, the protein migrates to 70-80 kDa (GARP)&13 kDa&42-50 kDa (Latent TGF Beta 1) based on Tris-Bis PAGE result.
