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

    ### mn-gly-gal-mn-combination With serum lot 4, combining 1 micromolar manganese and 1 millimolar galactose restored fully glycosylated LAMP2 more effectively than either alone. Condition category: machinery_impairment nutrient_topic: Manganese research collection; topical membership is not evidence of a direct dietary effect. plain_language: A combined supply improved a result that responded poorly to either component alone. organism: Homo sapiens tissue_or_cell_type: Golgi glycosylation in HEK cells experimental_model: TMEM165-knockout HEK cell cultures with different fetal bovine serum lots limitations: Serum manganese contributes to the result but is not the sole determinant. These are medium concentrations, not blood thresholds or supplementation regimens. exposure: Serum lot 4; 1 micromolar manganese, 1 millimolar galactose or both for 24 hours. cross_nutrient: Manganese(II) ion (combined_ion); D-Galactose (combined_sugar); TMEM165 Golgi cation-homeostasis protein (affected_protein) evidence_span: {"source_cache": "artifacts/manganese-glycosylation-sources/serum2020.txt", "locator": "Results and Figure 9; use 1 mM galactose from setup and legend, rather than the subsequent prose unit typo", "file_sha256": "203365df4c837f50483da9ec16cb0882674cf4903bbda21aa7374205d72ade69", "start_char": 9804, "end_char": 10848, "text_sha256": "3547ececbb7198f699bd64bcd033276f18a8e3d3b7c02c4f907f25a267444bec", "text_characters": 1044} [mn-gly-serum2020] Fetal bovine serum impacts the observed N-glycosylation defects in TMEM165 KO HEK cells.
