Related Product Information for
anti-Activin R2A antibody
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. They function through heteromeric complexes of type I and type II serine/threonine kinase receptors. Dimeric ligands bind to a type II receptor, such as Activin Receptor IIA (ActRIIA or activin R2A), which then associates with a type I receptor to initiate signal transduction. 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. Mature human 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 PDZbinding motif. Within the ECD, human ActRIIA shares 98% aa sequence identity with mouse and rat ActRIIA. Signaling through ActRIIA is modulated by its interaction with RGMB/ DRAGON, Cripto, Endoglin/CD105, TGFbeta RIII/Betaglycan, or BAMBI. These interactions can enhance ligandinduced signaling or interfere with signaling by preventing ActRIIA association with type I receptors. Activininduced responses can also be limited by the enhanced internalization of ActRIIA following its association with the cytoplasmic proteins ARIP1 and ARIP2.

NCBI Summary for Activin R2A
This gene encodes a receptor that mediates the functions of activins, which are members of the transforming growth factor-beta (TGF-beta) superfamily involved in diverse biological processes. The encoded protein is a transmembrane serine-threonine kinase receptor which mediates signaling by forming heterodimeric complexes with various combinations of type I and type II receptors and ligands in a cell-specific manner. The encoded type II receptor is primarily involved in ligand-binding and includes an extracellular ligand-binding domain, a transmembrane domain and a cytoplasmic serine-threonine kinase domain. This gene may be associated with susceptibility to preeclampsia, a pregnancy-related disease which can result in maternal and fetal morbidity and mortality. Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jun 2013]
UniProt Comments for Activin R2A
Function: On 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 A, activin B and inhibin A.

Catalytic activity: ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.

Cofactor: Magnesium or manganese

By similarity.

Subunit structure: Interacts with AIP1. Part of a complex consisting of AIP1, ACVR2A, ACVR1B and SMAD3

By similarity.

Subcellular location: Membrane; Single-pass type I membrane protein.

Sequence similarities: Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily.Contains 1 protein kinase domain.
