Component

Human PiT1 protein turnover

Human PiT1 protein turnover. Species, exposure and limitations are retained in each linked claim.

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.

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

  1. The study reported later XPR1-dependent modulation of PiT1 turnover, resetting phosphate uptake after the earlier efflux response.
