Component
SELENOP SECIS2
Independent entity for contextual scientific-audit claims; no universal nutritional effect implied.
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.

## secis2-first The second SECIS element mainly helps the first selenium insertion. SELENOP SECIS2 preferentially supports first-UGA decoding in the tested constructs. Organism: Zebrafish transcript in mammalian cells Cell type: Transfected cells Experimental model: SELENOP reporter SECIS/UGA mutations in mammalian cells Limitations: Functional preference, not exclusive wiring or a universal rate.
