Activin receptor type-2B is a protein that in humans is encoded by the ACVR2B gene. ACVR2B is an activin type 2 receptor. 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. Type II receptors are considered to be constitutively active kinases. This gene encodes activin A type IIB receptor, which displays a 3- to 4-fold higher affinity for the ligand than activin A type II receptor.
ACE-031 is intended for research purpose only. ACE-031 should not be used for human consumption, diagnostic, therapeutic procedures, agricultural and veterinary purposes.
ACE-031 is a soluble fusion protein that has been shown to increase muscle mass and strength in research studies.
ACE-031 is being studied as a treatment for metabolic diseases, renal neoplasms of childhood, cardiovascular anomalies, age-related muscle loss, and cancer treatment related muscle loss and neuromuscular diseases.
ACE-031 is a biologic therapeutic, based on activin receptor type IIB (ActRIIB). The molecule inhibits signaling via the ActRIIB receptor binding and increase muscle mass and strength. ACE-031 is a recombinant fusion protein that is artificially synthesized by fusion of standard antibody and a portion of ActRIIB receptor. The recombinant fusion protein eliminates myostatin and other biomolecules that limit muscle strength or growth.
