Pathway link SESN2-GATOR2

Sestrin2 GATOR2

Sestrin2 inhibits GATOR2.

When there's no leucine, Sestrin2 grabs onto GATOR2 and holds the whole growth pathway shut.

When leucine is scarce, free Sestrin2 clamps onto GATOR2 and blocks it, keeping the whole pathway switched off.

The conditions it holds under

Mammalian cell studies (CHA2014, PAR2014, WOL2015). Shows leucine sensing in cultured cells; the importance of this sensor in whole animals and people is not tested by these studies.

Studies behind it

YearEvidenceStudy
2014 M The Sestrins interact with GATOR2 to negatively regulate the amino-acid-sensing pathway upstream of mTORC1CHA2014 Sestrins bind GATOR2 to negatively regulate amino-acid signalling upstream of mTORC1.
2014 M Sestrins inhibit mTORC1 kinase activation through the GATOR complexPAR2014 Sestrins inhibit mTORC1 activation through the GATOR2 complex.
2015 M Sestrin2 is a leucine sensor for the mTORC1 pathwayWOL2015 Sestrin2 is a direct leucine sensor whose leucine binding releases GATOR2 to activate mTORC1.

Points the other way

No study in the Atlas contradicts this link. That means none in this curated set, not none in the literature.

“Inhibits” describes the effect on the target's activity, not on how much of it there is.

“How settled” describes how far researchers in the field agree. It is not the same as the sign-off above, which only says whether a named curator has checked this page.
