RICTOR (4H5) Antibody

RICTOR (Rapamycin-insensitive companion of mTOR) is a subunit of mTORC2, which regulates cell growth and survival in response to hormonal signals. Cell growth is a fundamental biological process whereby cells accumulate mass and increase in size. The mammalian TOR (mTOR) pathway regulates growth by coordinating energy and nutrient signals with growth factor-derived signals. mTOR is a large protein kinase with two different comple, Xenopus/Amphibian,es mTORC1 and mTORC2. One comple, Xenopus/Amphibian, contains mTOR, G(B)L and raptor, which is a target of rapamycin. The other comple, Xenopus/Amphibian,, insensitive to rapamycin, includes mTOR, G(B)L, Sin1 and rictor. The mTOR-rictor comple, Xenopus/Amphibian, phosphorylates Ser473 of Akt/PKB in vitro. This phosphorylation is essential for full Akt/PKB activation. Furthermore, an siRNA knockdown of rictor inhibits Ser473 phosphorylation in 3T3-L1 adipocytes. This comple, Xenopus/Amphibian, has also been shown to phosphorylate the rapamycin-resistant mutants of S6K1, another effector of mTOR .
