mTOR has also been called FRAP (FKBP-rapamycin-associated protein), RAFT (rapamycin and FKBP target), RAPT1, or SEP. The earlier names FRAP and RAFT were coined to reflect the fact that sirolimus must bind FKBP12 first, and only the FKBP12-sirolimus complex can bind mTOR. However, mTOR is now the widely accepted name, since Tor was first discovered via genetic and molecular studies of sirolimus-resistant mutants of Saccharomyces cerevisiae that identified FKBP12, Tor1, and Tor2 as the targets of sirolimus and provided robust support that the FKBP12-sirolimus complex binds to and inhibits Tor1 and Tor2.

Sin embargo, a diferencia del complejo tacrolimus/FKBP12 que inhibe la calcineurina (PP2B), el complejo sirolimus/FKBP12 inhibe la vía del mTOR (del inglés mammalian target of rapamycin) por la unión al complejo mTOR (mTORC1). El complejo mTOR es también llamado FRAP (del inglés FKBP-rapamycin associated protein) o RAFT (del inglés rapamycin and FKBP target). La denominación FRAP y RAFT son actualmente más adecuados dado que reflejan el hecho que el sirolimus debe unirse primero al FKBP12 y solo el complejo FKBP12/rapamycin puede unirse al FRAP/RAFT/mTOR.
