		Technical Data
A0855-91C1	ACVR1 (Activin Receptor Type 1, Activin Receptor Type I, ACTR-I, Serine/Threonine-protein Kinase Receptor R1, SKR1, Activin Receptor-like Kinase 2, ALK-2, TGF-B Superfamily Receptor Type I, TSR-I, ACVRLK2)

Description:
Activins are dimeric growth and differentiation factors which belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins. Activins signal through a heteromeric complex of receptor serine kinases which include at least two type I ( I and IB) and two type II (II and IIB) receptors. These receptors are all transmembrane proteins, composed of a ligand-binding extracellular domain with cysteine-rich region, a transmembrane domain, and a cytoplasmic domain with predicted serine/threonine specificity. Type I receptors are essential for signaling; and type II receptors are required for binding ligands and for expression of type I receptors. Type I and II receptors form a stable complex after ligand binding, resulting in phosphorylation of type I receptors by type II receptors. ACVR1 is an activin A type I receptor which signals a particular transcriptional response in concert with activin type II receptors.
