Pathway link SAM-SAMTOR

S-adenosylmethionine (SAM) ⊣ SAMTOR

S-adenosylmethionine (SAM) inhibits SAMTOR.

SAM, a byproduct of methionine, binds SAMTOR and pulls it away from GATOR1 – the proposed way the cell senses how much methionine it has. Worked out in cells; whether this sensor is what matters in a whole animal has not been shown.

S-adenosylmethionine, the cell's methyl-donor currency, binds SAMTOR and pulls it off GATOR1 - this is how methionine availability reaches mTORC1.

The conditions it holds under

Single-study edge. Needs independent replication before it is treated as established.

Time it takes

seconds

Step

direct (one molecule acts on the other)

Measured in

human cells

Where in the cell

cytosol

Reaches people?

plausible in people, not shown directly

How settled

emerging, few independent studies

Studies behind it

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.
