Anti-Activin A receptor type IB (ACVR1B, Activin receptor-like kinase 4, Activin receptor type 1B pr

The activin A receptor type 1 (ACVR1) is a membrane associated serine/threonine kinase receptor that binds activin A and TGF-beta superfaily growth factors, including bone morphogenetic protein 2 (BMP2) and BMP4, 6 and 7 (1-3). Functional activin receptors are composed of a pair of type I and type II activin receptor proteins. Following ligand binding, ACVR1 is phosphorylated by its type II binding partner, which allows recruitment and activation of receptor regulated SMAD (R-Smad) proteins (4). Phosphorylation of R-Smad proteins results in their translocation to the nucleus where R-Smads activate transcription of target genes (5). Mutations in the corresponding ACVR1 gene are associated with the genetic developmental disorders hereditary hemorrhagic telangiectasia and fibrodysplasia ossificans progressive (6,7). Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:1000. Incubate membrane with diluted antibody in 5% w/v BSA, 1X TBS, 0.1% Tween-20 at 4°C with gentle shaking, overnight. , Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
