The macrolide antibiotic rapamycin and the cytosol protein FKBP12 can form a complex which specifically inhibits the TORC1 complex, leading to growth arrest. The FKBP12-rapamycin complex interferes with TORC1 function by binding to the FKBP12-rapamycin binding domain (FRB) of the TOR proteins. This entry represents the FRB domain [1, 2].	Domain
