復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

功能：

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.

1. The current study reveals that ActRIIB activation by activin A induces muscle catabolism primarily through the activation of p38beta MAPK-mediated catabolic signalling that activates the ubiquitin-proteasome pathway and the autophagy-lysosome pathway. PMID: 27897407
2. The endoplasmic reticulum stress stress and unfolded protein response are increased in mdx muscle. However, these processes are not distinctly improved by voluntary exercise or blocking activin receptor IIB ligands and thus do not appear to be optimal therapeutic choices for improving proteostasis in Duchenne muscular dystrophy. PMID: 27554968
3. Data, including data from studies using transgenic mice, suggest that osteoblasts deficient in Acvr2A exhibit un-characteristic features; osteoclasts deficient in Acvr2A or Acvr2B or both appear normal. Acvr2A-deficient mice exhibit significantly increased femoral trabecular bone volume at 6 weeks of age; Acvr2B-deficient mice exhibit no significant change in any bone parameter. PMID: 28659341
4. Differential muscle hypertrophy is associated with satellite cell numbers and Akt pathway activation following activin type IIB receptor inhibition in Mtm1 PMID: 24726641
5. ActRIIB inhibition enhanced energy expenditure only at ambient temperature or in the cold, where nonshivering thermogenesis is minimal, suggesting that brown fat activation plays a prominent role in the metabolic actions of ActRIIB inhibition. PMID: 22586266
6. findings best fit a model in which BMP3, produced by mature bone cells, acts to reduce BMP signaling through Acvr2b in skeletal progenitor cells, limiting their differentiation to mature osteoblasts PMID: 22074949

13. genetic evidence strongly suggested that ActRIIB and Smad2 function in the same signaling pathway to regulate axial patterning and pancreas islet formation by means of a threshold mechanism. PMID: 17849440
14. expression of MSTN and its associated binding proteins can be modulated in adipose tissue and skeletal muscle by chronic obesity PMID: 18334608
15. Data suggest that BMP3 exerts its effects in the skeleton by altering signaling through ActRIIB in chondrocytes and the periosteum, and this results in defects in bone collar formation and late hypertrophic chondrocyte maturation. PMID: 19653325
