Gene Description

RPTOR (Raptor) is the defining substrate-presenting subunit of mTOR complex 1 (mTORC1). It is a non-catalytic molecular adaptor with two roles within the complex: it mediates recruitment of mTORC1 to the lysosomal surface by binding the Rag GTPases, and it confers substrate specificity by binding TOS-motif-containing substrates (e.g. EIF4EBP1/4E-BP1 and RPS6KB1/S6K1) and directing them to the active site of the MTOR kinase. Through mTORC1 it couples nutrient, growth-factor and energy signals to the control of cell growth, protein synthesis, autophagy and metabolism.

KEEP AS NON CORE
Summary: Downstream growth regulation; non-core.
Reason: Regulation of cell growth is a downstream output of mTORC1 signalling; true but peripheral to RPTOR's core adaptor MF. Non-core.
GO:0001938 positive regulation of endothelial cell proliferation
IEA
GO_REF:0000107
KEEP AS NON CORE
Summary: Distal proliferation output; non-core.
Reason: Positive regulation of endothelial cell proliferation (IEA) is a distal, tissue-level consequence of mTORC1 activity; non-core.

ACCEPT
Summary: contributes_to the mTORC1 kinase activity (subunit); keep.
Reason: RPTOR is non-catalytic but is annotated with the contributes_to qualifier to the mTORC1 serine/threonine kinase activity, the correct way to credit a complex subunit for the complex's catalytic activity. Keep.

Summary: Partner is the MTOR kinase; recast as protein kinase binding.
Reason: Interaction partner is the MTOR kinase (UniProtKB:P42345 / mouse ortholog); binding the catalytic subunit of mTORC1 is informatively protein kinase binding, not bare protein binding. This contact is the enzyme side of RPTOR's enzyme-substrate adaptor role.

Summary: Interactor is RPS6KB1/S6K1, a protein kinase; recast as protein kinase binding.
Reason: The interaction partner is RPS6KB1 (S6K1, UniProtKB:P23443), a protein kinase that RPTOR binds via its TOS motif as an mTORC1 substrate. A binary interaction evidences binding, so the supported refinement is protein kinase binding; the bridging enzyme-substrate adaptor activity itself is already asserted by IDA (GO:0140767).

This is a binary protein-binding (IPI) hit; it evidences binding, not the enzyme-substrate adaptor (bridging) activity, which is already asserted by IDA (GO:0140767).

Summary: Interactor is RPS6KB1/S6K1, a protein kinase; recast as protein kinase binding.
Reason: The interaction partner is RPS6KB1 (S6K1, UniProtKB:P23443), a protein kinase that RPTOR binds via its TOS motif as an mTORC1 substrate. A binary interaction evidences binding, so the supported refinement is protein kinase binding; the bridging enzyme-substrate adaptor activity itself is already asserted by IDA (GO:0140767).

Reason: The partner is EIF4EBP1/4E-BP1 (UniProtKB:Q13541), a TOS-motif mTORC1 substrate. This is a binary protein-binding (IPI) hit; it evidences binding, not the enzyme-substrate adaptor (bridging) activity, which is already asserted by IDA (GO:0140767). A binding term for this partner would be uninformative, so the bare protein-binding row is removed under the protein-binding policy.

Core Functions

Substrate-specific adaptor: within mTORC1, RPTOR binds TOS-motif substrates (4E-BP1, S6K1) and presents them to the MTOR kinase, conferring substrate specificity on the complex.

Directly Involved In:
Cellular Locations:
In Complex:
TORC1 complex
Supporting Evidence:
  • PMID:12747827
    TOS motif-mediated raptor binding regulates 4E-BP1 multisite phosphorylation
  • PMID:24403073
    Raptor in mTOR complex 1 is believed to recruit 4E-BP1, facilitating phosphorylation of 4E-BP1 by the kinase mTOR.

Recruitment adaptor: RPTOR binds the Rag GTPases to recruit and dock mTORC1 at the lysosomal membrane, where the complex is activated by nutrients.

Supporting Evidence:
  • PMID:37541260
    facilitates the interactions between Raptor and Rag GTPases and promotes the translocation of mTOR to the lysosomal surface
  • PMID:26588989
    NLK phosphorylates Raptor on S863 to disrupt its interaction with the Rag GTPase, which is important for mTORC1 lysosomal recruitment.
