Technical Data
Activin A Receptor Type IB (ACVR1B, Activin Receptor-like Kinase 4, Activin Receptor Type 1B Precursor, ACTR-IB, ACVRLK4, ALK4)
The activin A receptor type 1 (ACVR1) is a membrane associated serine/threonine kinase receptor that binds activin A and TGF-B 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).

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 4C with gentle shaking, overnight.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. 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.
