NCIt definition : Activin receptor type-1C (493 aa, 55 kDa) is encoded by the human ACVR1C gene. This
protein plays a role in both cytokine signaling and serine/threonine phosphorylation.;
NCIt note : Activin receptor type-1C forms a receptor complex on ligand binding which consists
of 2 type II and 2 type I transmembrane serine/threonine receptor kinases. Type II
receptors phosphorylate and activate type I receptors which autophosphorylate. Phosphorylated
type I receptors then bind and phosphorylate SMAD2 and SMAD3. (UniProt);
