NCIt synonyms : Activin Receptor-Like Kinase 4; Activin A Receptor, Type II-Like Kinase 4; Serine/Threonine-Protein Kinase Receptor R2; SKR2; ACTR-IB; ALK-4; Activin Receptor Type IB; Activin A Type IB Receptor; EC 2.7.11.30; Activin-A Type-B Receptor;
NCIt definition : Activin receptor type-1B (505 aa, 57 kDa) is encoded by the human ACVR1B gene. This
protein plays a role in protein phosphorylation, signal transduction, cell cycle regulation
and apoptosis.;
NCIt note : Type I receptors are essential for transmembrane 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.;
