Description

ACVR2B plays a central role in TGF-β superfamily signaling by serving as a high-affinity receptor for activins, myostatin, and GDF-11, making it a key target in muscle biology and metabolic disease research. This recombinant human ACVR2B encompasses the extracellular ligand-binding domain (aa 19–134) with a C-terminal His-Fc tag, expressed in mammalian cells to preserve native glycosylation and conformational integrity critical for accurate ligand recognition. Functional ELISA confirms that immobilized Activin A (2 μg/ml) binds this protein with an ED50 of 50–500 ng/ml, providing validated support for receptor-ligand interaction assays, competitive inhibition studies, blocking antibody screening, and use as a positive control in ELISA, SPR, or BLI-based affinity characterization. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the quality criteria typical for drug discovery screening of small-molecule or biologic inhibitors targeting the activin signaling axis.

Target Background

Function

Transmembrane serine/threonine kinase activin type-2 receptor forming an activin receptor complex with activin type-1 serine/threonine kinase receptors (ACVR1, ACVR1B or ACVR1c). Transduces the activin signal from the cell surface to the cytoplasm and is thus regulating many physiological and pathological processes including neuronal differentiation and neuronal survival, hair follicle development and cycling, FSH production by the pituitary gland, wound healing, extracellular matrix production, immunosuppression and carcinogenesis. Activin is also thought to have a paracrine or autocrine role in follicular development in the ovary. Within the receptor complex, the type-2 receptors act as a primary activin receptors (binds activin-A/INHBA, activin-B/INHBB as well as inhibin-A/INHA-INHBA). The type-1 receptors like ACVR1B act as downstream transducers of activin signals. Activin binds to type-2 receptor at the plasma membrane and activates its serine-threonine kinase. The activated receptor type-2 then phosphorylates and activates the type-1 receptor. Once activated, the type-1 receptor binds and phosphorylates the SMAD proteins SMAD2 and SMAD3, on serine residues of the C-terminal tail. Soon after their association with the activin receptor and subsequent phosphorylation, SMAD2 and SMAD3 are released into the cytoplasm where they interact with the common partner SMAD4. This SMAD complex translocates into the nucleus where it mediates activin-induced transcription. Inhibitory SMAD7, which is recruited to ACVR1B through FKBP1A, can prevent the association of SMAD2 and SMAD3 with the activin receptor complex, thereby blocking the activin signal. Activin signal transduction is also antagonized by the binding to the receptor of inhibin-B via the IGSF1 inhibin coreceptor.
