Component

NFATC1

Independent biological entity. Read linked claims for experimental scope and context.

2 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.

  1. AM404 was a potent inhibitor of T-cell-receptor-mediated T-cell activation, specifically inhibiting interleukin-2 and tumour necrosis factor alpha gene transcription and tumour necrosis factor alpha synthesis in stimulated Jurkat T cells in a fatty acid amide hydrolase independent way, inhibiting both the binding to DNA and the transcriptional activity of endogenous nuclear factor of activated T cells without affecting early steps such as calcium mobilization or dephosphorylation, and without interfering with the pathways leading to AP-1 or nuclear factor kappa B activation.
