Abstract
The invention relates to the human protein FRAP, and in particular to the FKBP12-rapamycin binding domain thereof and to the ternary complex formed by the FRB domain, rapamycin and FKBP12. A new crystalline composition comprising the ternary complex, coordinates defining its three dimensional structure in atomic detail, and uses thereof are disclosed.
