Background: Activin RIIA

Activin proteins are involved in a wide range of biological processes including mesoderm induction, neural cell differentiation, bone remodeling, hematopoiesis, the regulation of reproductive physiology, inflammation, and carcinogenesis (1 ‑ 3). They function through heteromeric complexes of type I and type II serine/threonine kinase receptors (2, 4). Dimeric ligands bind to a type II receptor, such as Activin Receptor IIA (ActRIIA), which then associates with a type I receptor to initiate signal transduction (4). ActRIIA mediates the pleiotropic effects of Activins and Inhibins as well as several members of the BMP and GDF families of TGF-beta like proteins (4). Mature mouse ActRIIA is a 70 kDa glycoprotein that consists of a 116 amino acid (aa) extracellular domain (ECD), a 26 aa transmembrane segment, and a 352 aa cytoplasmic region that includes the kinase domain and a PDZ-binding motif (5). Within the ECD, mouse ActRIIA shares 98% and 100% aa sequence identity with human and rat ActRIIA, respectively. Signaling through ActRIIA is modulated by its interaction with RGM-B/DRAGON, Cripto, Endoglin/CD105, TGF-beta RIII/Betaglycan, or BAMBI (6 - 10). These interactions can enhance ligand-induced signaling or interfere with signaling by preventing ActRIIA association with type I receptors (6 - 9). Activin-induced responses can also be limited by the enhanced internalization of ActRIIA following its association with the cytoplasmic proteins ARIP1 and ARIP2 (11, 12).
