This product (recombinant mTOR/Raptor/MLST8) is a complex of human mechanistic target of rapamycin (mTOR), also known as FRAP1 (GenBank Accession No. NM_004958), amino acids 1362-end with N-terminal FLAG-tag, MW = 137 kDa; human mTOR associated protein, LST8 homolog (MLST8) (GenBank Accession No. NM_022372) amino acids 2-326 (end) with N-terminal His-tag, MW = 37 kDa and human regulatory associated protein of MTOR complex 1 (Raptor) (GenBank Accession No. NM_020761) amino acids 2-1335 (end) with N-terminal His-tag, MW=150 kDa, co-expressed in a Baculovirus-infected Sf9 cell expression system.

Recombinant mTOR/Raptor/MLST8 has been used in in vitro caspase reactions.

Mechanistic target of rapamycin (mTOR) modulates cell growth and division by integrating nutrient and mitogen signals. It also modulates the functions of antigen-presenting cells, like dendritic cells and activates T-cells. mTOR is also involved in innate and adaptive immunity. mTOR associated protein, LST8 homolog (MLST8) is a subunit of both the mTOR complex 1 and 2 (mTORC1 and 2). It is crucial for the activation of the mTOR kinase and is a regulator of mTOR pathways. Regulatory-associated protein of mTOR complex 1 (RAPTOR) has an important role in modulating cell growth and energy homeostasis as a scaffolding protein. It takes part in recruiting substrates of the mechanistic target of rapamycin (mTOR) to the rapamycin-sensitive mTOR complex 1 (mTORC1). RAPTOR also associates with proteins involved in the pathway and aids in phosphorylating them.
