SMAD2 mediates the signal of the transforming growth factor (TGF)-beta, and thus regulates multiple cellular processes, such as cell proliferation, apoptosis, and differentiation. This protein is recruited to the TGF-beta receptors through its interaction with the SMAD anchor for receptor activation (SARA) protein. In response to TGF-beta signal, this protein is phosphorylated by the TGF-beta receptors. The phosphorylation induces the dissociation of this protein with SARA and the association with the family member SMAD4. The association with SMAD4 is important for the translocation of this protein into the cell nucleus, where it binds to target promoters and forms a transcription repressor complex with other cofactors. This protein can also be phosphorylated by activin type 1 receptor kinase, and mediates the signal from the activin. Alternatively spliced transcript variants encoding the same protein have been observed.
Smad2 Polyclonal Antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. This antibody has been tested with ELISA, IF, IHC-p, WB. And Abbkine suggested starting dilutions are as follows: WB: 1:500-1:2000, IHC-p: 1:100-1:300, IF: 1:200-1:1000, ELISA: 1:5000.
To my knowledge, Abbkine is a great option when you want to find a cost-effective product. It is worth recommending. I’ve tried Smad2 Polyclonal Antibody with excellent results.
