RESUMEN

S100A6, as a member of S100 protein family, have biological functions in cell proliferation, differentiation, morphology, cytoskeletal organization and apoptosis. In the last three decades, S100A6 has been caught more and more attention. Here, we introduced a simple and efficient method for producing high-purity recombinant human S100A6 from Escherichia coli culture with low level of endotoxin. We further demonstrated its biological activities for triggering SH-SY5Y cells apoptosis in vitro. These results can facilitate the study of physiological and pathological roles of S100A6 and other members of S100 family proteins.
