The roles of the extracellular domain of type II TGF-β receptor (TBRII-ECD) in physiological processes ranging from development to cancer to wound healing render it an attractive target for exploration with chemical tools. For such applications, large amounts of active soluble protein are needed, but the yields of TBRII-ECD we obtained with current folding protocols were variable ...
