Component
Membrane-to-cytosol APT2 ratio in human cells
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Sulforaphane reduced the membrane-to-cytosol ratio of FLAG-tagged APT2 in HEK293 fractionation experiments.

- experimental_model
- Human HEK293 expressing FLAG-tagged human APT2
- exposure
- 100 micromolar sulforaphane for 3 hours; membrane and cytosol fractions with pan-cadherin and alpha-tubulin markers; three separate experiments.
- limitations
- These are separate experimental observations, not a demonstrated sulforaphane-GPX4-ZDHHC6 pathway. Sulforaphane-driven APT2 relocalization is not equivalent to genetic depletion or general catalytic inhibition. No dietary, clinical or selenium-repletion effect is inferred. Protein stability, palmitoylation and substrate output remain different measurements. The authors describe plasma-membrane localization, but fractionation is not an ER-specific or organelle-resolved measurement.
