Description

The TGFβ (transforming growth factor β) superfamily proteins are pleiotropic cytokines that regulate a diverse range of cellular processes, including proliferation, differentiation, migration, adhesion and death.  The TGFβ superfamily elicits 4 signaling pathways: TGFβ, Bone Morphogenic Protein (BMP), Activin, and Nodal.  Each pathway signals through a heteromeric receptor complex composed of at least two type-I and two type-II transmembrane receptors containing cytoplasmic serine/threonine kinase domains. These receptors are distinguished by the presence of a glycine/serine-rich juxta-membrane domain found only in the type I receptors. Either type receptor may initially bind ligand, followed by the recruitment of an alternate-type receptor counterpart to form a signal-activating complex. The type I receptors are also referred to as ALKs (Activin receptor-like kinases). TGFBR1 (transforming growth factor β receptor I), also known as ALK5, SKR4, and ACVRLK4, is a type I receptor for TGFβ that functions as a tumor suppressor by inhibiting the cell cycle in the G1 phase. TGFBR1 may play an important role in development.  Mice deficient in TGFBR1 die at midgestation with severe defects in vascular development and an absence of circulating red blood cells. Defects in TGFBR1 are the cause of Loeys-Dietz syndrome type 1A (LDS1A), Loeys-Dietz syndrome type 2A (LDS2A), and aortic aneurysm familial thoracic type 5 (AAT5).  TGFBR1 is involved in proper lymphatic network development. Mutations in TGFBR1 have been identified in multiple human cancers, such as pancreatic, colorectal, ovarian, and head and neck cancers.
