Spermidine/spermine N1-acetyltransferase 1

SAT1gene

Polyamine acetyltransferase linked to lactate–lactylation signaling in acute myocardial injury.

Pathway placement

Cascade stepOff-pathway / systemic markers

Confidencelow

RationaleLactylation marker; polyamine metabolism in stress, off-cascade.

Druggability

Not assessed (no mapped human gene target).

Assay & specimen

Class-level default (no specific cleared assay)— generic method inferred from analyte class; confirm against a specific product insert before use.

Specimen

Whole blood — gene is not a circulating analyte; measure protein product or genotype

Collection tube

K2-EDTA whole blood (lavender-top)

Method / principle

SNP genotyping / sequencing; or immunoassay of encoded protein

Reagent / substrate

Allele-specific primers/probes (TaqMan) or NGS panel; or antibody for protein

Platform

qPCR / NGS / array
