"We have found that in HEK293 cells and 3T3-L1 adipocytes, insulin promotes both raptor- and rictor-associated mTOR Ser(P)-2481 in a wortmannin-sensitive manner. Thus, insulin signals via PI3K to promote both mTORC1- and mTORC2-associated mTOR Ser-2481 autophosphorylation."

"We report here the identification of a FRAP autophosphorylation site. This site, Ser-2481, is located in a hydrophobic region near the conserved carboxyl-terminal FRAP tail. We demonstrate that the COOH-terminal tail is required for FRAP kinase activity and for signaling to the translational regulator p70(s6k) (ribosomal subunit S6 kinase)."
