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). ACVR1 (Activin receptor type-1), also known as ACVR1A, ALK2, FOP, SKR1, TSRI, ACVRLK2, and ActRI, is a type I receptor in the TGFβ receptor family.  ACVR1 was identified as a receptor for both Activin and BMP.  It is expressed in normal parenchymal cells, endothelial cells, fibroblasts and tumor-derived epithelial cells.  ACVR1 plays a critical role in gastrulation, skeletal system development, and cardiac morphogenesis. It may be required for left-right pattern formation during embryogenesis.  Overexpression of ACVR1 causes a mitotic arrest. ACVR1 can phosphorylate the co-receptor Endoglin and mediate the inhibitory effect of Endoglin on prostate cancer cell motility.  Defects in ACVR1 are associated with fibrodysplasia ossificans progressiva (FOP).
