Background

TGF-beta RI, also called ALK-5, is an approximately 55 kDa type I transmembrane serine/threonine receptor kinase (1, 2). It contains a cysteine-rich extracellular domain (ECD), a transmembrane helix, and a C-terminal cytoplasmic kinase domain (3). Within the cytoplasmic domain there is also a short, conserved regulatory sequence known as the GS region that is N-terminal to the kinase domain (1). Within the ECD, human TGF-beta RI shares 90% and 88% aa sequence identity with mouse and rat TGF-beta RI, respectively. In the presence of TGF-beta , TGF-beta RI forms a complex with, and is phosphorylated by, TGF-beta RII (1). Phosphorylated TGF-beta RI can then transiently bind and phosphorylate Smad2 and Smad3 (2, 4-6). These phosphorylated Smads form heteromeric complexes with Smad4, translocate to the nucleus, and regulate target gene transcription (2, 4-6). TGF-beta RI is likely important during development, since mice deficient for TGF-beta RI die at midgestation with severe defects in vascular development of the yolk sac and placenta, and an absence of circulating red blood cells (7). Furthermore, TGF-beta RI appears to be involved in proper lymphatic network development (8). Mutations in TGF-beta RI have been identified in pancreatic, colorectal, ovarian, and head and neck cancers (9).
