Abstract excerpt
We used olefin metathesis to synthesize C40 derivatives of FK506 and measured their ability, when complexed to FKBP12, to inhibit calcineurin's phosphatase activity. We identified modular dimerization domains (CABs) containing segments of the calcineurin A and B polypeptides. These CABs respond to FK506 both when overexpressed in mammalian cells and in yeast or mammalian three-hybrid assays. Using chemical...
