The S100A4 protein is a calcium-binding protein involved in angiogenesis, cell differentiation, apoptosis, and autophagy. S100A4 protein interacts with MYH9 to enhance cell motility and invasion. S100A4 also inhibits the pro-apoptotic function of TP53 by reducing its protein levels. S100A4 Protein, Human (C-His) is the recombinant human-derived S100A4 protein, expressed by E. coli , with C-6*His labeled tag. The total length of S100A4 Protein, Human (C-His) is 101 a.a., with molecular weight of ~13.0 kDa.
