  • FunctionOn ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for activin. May be involved for left-right pattern formation during embryogenesis.
  • Tissue specificityExpressed in normal parenchymal cells, endothelial cells, fibroblasts and tumor-derived epithelial cells.
  • Involvement in diseaseDefects in ACVR1 are a cause of fibrodysplasia ossificans progressiva (FOP) [MIM:135100]. FOP is a rare autosomal dominant disorder of skeletal malformations and progressive extraskeletal ossification. Heterotopic ossification in FOP begins in childhood and can be induced by trauma or may occur without warning. Bone formation is episodic and progressive, leading to extra-articular ankylosis of all major joints of the axial and appendicular skeleton, rendering movement impossible.
  • Sequence similaritiesBelongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily.
    Contains 1 GS domain.
    Contains 1 protein kinase domain.
