RICTOR (Rapamycin-insensitive companion of mTOR) is a gene. The public catalogues list it as a drug target and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Gastric & gastro-oesophageal junction cancer, Lung cancer, Breast cancer and 5 more.
Component of the mechanistic target of rapamycin complex 2 (mTORC2), which transduces signals from growth factors to pathways involved in proliferation, cytoskeletal organisation, lipogenesis and anabolic output. In response to growth factors, mTORC2 phosphorylates and activates AGC protein kinase family members, including AKT (AKT1, AKT2 and AKT3), PKC (PRKCA, PRKCB and PRKCE) and SGK1. In contrast to mTORC1, mTORC2 is nutrient-insensitive.
CIViC holds 4 clinical evidence items and 0 assertions across 1 variant, naming Vistusertib, Sapanisertib, MTOR Kinase Inhibitor AZD8055 and Onatasertib. Open Targets scores its association with cancer at 0.66 (direct and indirect evidence; datatypes literature 0.98, affected pathway 0.61, genetic association 0.00, somatic mutation 0.98).

No product in this corpus aims at RICTOR yet. Drugs bind the molecule precisely: to switch it off, flag the cell for the immune system, or deliver a payload.
Broadly expressed or essential: HPA lists RICTOR among essential proteins and finds the RNA at low tissue specificity; a medicine acting on the wild-type protein would expose normal tissue too. HPA RICTOR: RNA low tissue specificity; blood lineage lineage enriched (granulocytes 31 nTPM); high antibody staining in 14 normal tissues; highest cancer staining endometrial cancer (5 of 11 high). Distribution: 5 cancer families in the corpus carry a prevalence row, label threshold or catalogue link for it (Gastric & gastro-oesophageal junction cancer, Lung cancer (all types), Breast cancer (all types), Skin cancer (all types), Colorectal cancer); Open Targets associates it with 0 specific cancer types at or above 0.5.

Component of the mechanistic target of rapamycin complex 2 (mTORC2), which transduces signals from growth factors to pathways involved in proliferation, cytoskeletal organisation, lipogenesis and anabolic output. In response to growth factors, mTORC2 phosphorylates and activates AGC protein kinase family members, including AKT (AKT1, AKT2 and AKT3), PKC (PRKCA, PRKCB and PRKCE) and SGK1. In contrast to mTORC1, mTORC2 is nutrient-insensitive. Within the mTORC2 complex, RICTOR probably acts as a molecular adapter. RICTOR is responsible for the FKBP12-rapamycin-insensitivity of mTORC2. mTORC2 plays a critical role in AKT1 activation by mediating phosphorylation of different sites depending on the context, such as 'Thr-450', 'Ser-473', 'Ser-477' or 'Thr-479', facilitating the phosphorylation of the activation loop of AKT1 on 'Thr-308' by PDPK1/PDK1 which is a prerequisite for full activation. mTORC2 catalyses the phosphorylation of SGK1 at 'Ser-422' and of PRKCA on 'Ser-657'. The mTORC2 complex also phosphorylates various proteins involved in insulin signalling, such as FBXW8 and IGF2BP1. mTORC2 acts upstream of Rho GTPases to regulate the actin cytoskeleton, probably by activating one or more Rho-type guanine nucleotide exchange factors. mTORC2 promotes the serum-induced formation of stress-fibres or F-actin.
