Identification of the novel interacting partners of the mammalian target of rapamycin complex 1 in human CCRF-CEM and HEK293 cells.

ABSTRACT: The present study was undertaken to identify proteins that interact with the mammalian target of rapamycin complex 1 (mTORC1) to enable it to carry out its crucial cell signaling functions. Endogenous and myc-tag mTORC1 was purified, in-gel tryptic digested and then identified by nano-LC ESI Q-TOF MS/MS analysis. A total of nine novel interacting proteins were identified in both endogenous and myc-tag mTORC1 purifications. These new mTORC1 interacting partners include heterogeneous nuclear ribonucleoproteins A2/B1, enhancer of mRNA decapping protein 4, 60S acidic ribosomal protein, P0, nucleolin, dynamin 2, glyceraldehyde 3 phosphate dehydrogenase, 2-oxoglutarate dehydrogenase, glycosyl transferase 25 family member 1 and prohibitin 2. Furthermore hnRNP A2/B1 and dynamin 2 interaction with
