Structure of 14-3-3 in complex with the differentiation-inducing agent Cotylenin AStructure of 14-3-3 in complex with the differentiation-inducing agent Cotylenin A
Structural highlights
FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedCotylenin A, a fungal metabolite originally described as a cytokinin-like bioactive substance against plants shows differentiation-inducing and anti-tumor activity in certain human cancers. Here, we present the crystal structure of cotylenin A acting on a 14-3-3 regulatory protein complex. By comparison with the closely related, but non-anticancer agent fusicoccin A, a rationale for the activity of cotylenin A in human cancers is presented. This class of fusicoccane diterpenoids are possible general modulators of 14-3-3 protein-protein interactions. In this regard, specificities for individual 14-3-3/target protein complexes might be achieved by varying the substituent pattern of the diterpene ring system. As the different activities of fusicoccin A and cotylenin A in human cancers suggest, hydroxylation of C12 might be a sufficient determinant of structural specificity.
