Description

This recombinant monoclonal antibody is designed as a research-grade biosimilar to Bimagrumab, targeting activin receptor type 2B (ACVR2B), a transmembrane serine/threonine kinase receptor. ACVR2B plays a critical role in regulating skeletal muscle mass by mediating signaling of activin and myostatin, both negative regulators of muscle growth. Upon ligand binding, ACVR2B initiates downstream SMAD signaling cascades that inhibit muscle protein synthesis and promote protein degradation. Dysregulation of ACVR2B signaling is implicated in muscle-wasting conditions including sarcopenia, cachexia, and various muscular dystrophies, making this pathway an important therapeutic target for preserving muscle mass and function.

Bimagrumab is a fully humanizedized monoclonal antibody that blocks ACVR2B, preventing the binding of its ligands and thereby promoting muscle growth and maintenance. This biosimilar antibody serves as a valuable research tool for investigating ACVR2B biology, exploring muscle homeostasis mechanisms, and studying potential interventions for muscle-wasting disorders. It enables researchers to examine the therapeutic potential of ACVR2B inhibition in preclinical models and advance understanding of skeletal muscle regulation.

Usage

It is a non-therapeutic biosimilar antibody, owning the same variable region from the corresponding approved therapeutic antibody. In conclusion, it is a research-grade biosimilar antibody and expressed in mammalian cell, which can be directly used as positive controls in drug discovery or used for rapid verification of the biological functions of target protein.

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.
