Transforming Growth Factor Beta Receptor 3,Bgcan,Betaglycan,Tgfbr3
Most mammalian cells express three abundant high affinity receptors, which can bind and be cross-linked to TGF beta: the type I (53 kDa), type II (65 kDa), and type III (100-280 kDa) receptors, based upon the molecular mass of the cross-linked products analyzed by gel electrophoresis. Tbeta-RI and Tbeta-RII, the type I and II receptors, are type I transmembrane proteins with cytosolic domains containing a serine-threonine kinase. Both receptors are essential for signal transduction. The TGF beta type III receptor, or betaglycan, is a membrane-bound proteoglycan with a short cytoplasmic tail that has no apparent signaling motif. It binds TGF beta 2 (apparent Kd 100 pM) with slightly greater affinity than TGF beta 1 or TGF beta 3 (apparent Kda 300 pM). The main role of betaglycan seems to be in binding and then presenting TGF beta ligand to the signaling receptors Tbeta-RI and Tbeta-RII; overexpression of Tbeta-RIII in L6 myoblasts leads to a dramatic increase in TGF beta 2 binding to Tbeta-RI and Tbeta-RII.
