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.

Condition category: normal nutrient_topic: Manganese research collection; topical membership is not evidence of a direct dietary effect. plain_language: Zn(II) competed with manganese entry through ZIP14 in this assay. organism: Mouse protein in Xenopus laevis oocytes tissue_or_cell_type: Oocyte plasma membrane experimental_model: Mouse ZIP14 in RNA-injected Xenopus laevis oocytes limitations: A tenfold molar competitor in a heterologous system is not a dietary competition threshold. exposure: 2 micromolar radiolabeled Mn(II) with candidate inhibitor metal at 20 micromolar and 1 mM L-ascorbic acid; Figure 9B. cross_nutrient: true [mn-trans-21653899] Zip14 is a complex broad-scope metal-ion transporter whose functional properties support roles in the cellular uptake of zinc and nontransferrin-bound iron.
