The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.5 µg/ml. Detects a band of approximately 39 kDa (predicted molecular weight: 44 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
功能Transcriptional activator. Recognizes and binds to the DNA sequence 5'-TGT[GT][GT]ATT-3'. Required for induction of the goosecoid (GSC) promoter by TGF-beta or activin signaling. Forms a transcriptionally active complex containing FOXH1/SMAD2/SMAD4 on a site on the GSC promoter called TARE (TGF-beta/activin response element).
序列相似性Contains 1 fork-head DNA-binding domain.
结构域The FM region is required for binding SMAD2/SMAD4 complexes. FM2 is more effective than FM1 and only interacts with phosphorylated SMAD2 that is in an activated SMAD complex.
