TGFBR2, TGF-beta receptor type-2, TGFR-2, TGF-beta type II receptor, Transforming growth factor-beta receptor type II, TGF-beta receptor type II, TbetaR-II
TGFbetas mediate their activity by high affinity binding to the type II receptor (TGFbeta RII) transmembrane protein with a cytoplasmic serine-threonine kinase domain. For signaling growth inhibition and early gene responses the type II receptor requires both its kinase activity and association with a TGFbeta-binding protein, designated the type I receptor. Two independent groups have recently described the cloning and sequence analysis of genes encoding TGFbeta type I receptor proteins designated ALK-5 (TbetaR-1) and TSR-1, respectively.
