  • Immunohistochemistry
  • Immunohistochemistry-Paraffin
Application Notes
This SAT1 antibody is useful for Western Blot, Immunocytochemistry/Immunofluorescence, and Immunohistochemistry paraffin embedded sections. In Western Blot analysis on transfected lysates a band is seen at ~27 kDa. ICC/IF, cytoplasmic staining was observed in U2OS cells. In IHC-P, strong staining was observed in the cytoplasm with some weak nuclear staining in mouse seminal vesical and prostate tissue. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.

The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Theoretical MW
27 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Reactivity Notes

Immunogen sequence has 86% homology to Zebrafish.

SAT1 or spermidine/spermine N(1)-acetyltransferase 1 (also called SSAT, diamine acetyltransferase 1 and putrescine acetyltransferase) is a homodimeric cytoplasmic enzyme which belongs to acetyltransferase family and catalyzes acetylation of polyamines. SAT1's substrate specificity order is: norspermidine = spermidine >spermine > N(1)-acetylspermine > putrescine, and its activity is highly regulated that allows a fine attenuation of the intracellular polyamines concentrations via acetylation or polyamine export. Polyamines such as putrescine, spermidine and spermine are implicated in the regulation of cellular growth/proliferation (increased levels leads to cancer progression) and their levels are controlled by several catabolic enzymes which includes such as SAT1, APAO (acetylpolyamine oxidase) and SMO (spermine oxidase). Enhanced SSAT expression has been shown to be associated with apoptosis in cancer cells and SSAT was shown to decrease the expression of anti-apoptosis-related signaling proteins AKT and mTOR. SAT1 has also been implicated in the neurobiology of suicide and decreased SAT1 expression has been observed in several brain regions in suicide completers. Defects in SAT1 may be a cause of keratosis follicularis spinulosa decalvans X-linked (KFSDX).
