|Detection of Human Cytosolic Sulfotransferase 4A1/SULT4A1 by Western Blot. Western blot shows lysates of human brain (cortex) tissue. PVDF Membrane was probed with 2 µg/mL of Human Cytosolic Sulfotransferase 4A1/SULT4A1 Monoclonal Antibody (Catalog # MAB5826) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Cytosolic Sulfotransferase 4A1/SULT4A1 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.|
|Cytosolic Sulfotransferase 4A1/SULT4A1 in Human Brain. Cytosolic Sulfotransferase 4A1/SULT4A1 was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using Human Cytosolic Sulfotransferase 4A1/SULT4A1 Monoclonal Antibody (Catalog # MAB5826) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

Cytosolic SULT4A1 (Sulfotransferase 4A1 also BR-STL1/Brain sulfotransferase-like protein) is a 33-36 kDa member of the sulfotransferase 4 family of enzymes. SULT4A1 message is widely expressed. However, it appears to be translated only in brain. SULT4A is very unusual in that it is the only SULT that shows minimal activity on synthetic laboratory substrates. Instead, it acts on catecholamines and T4 in a manner that may not involve sulfonation. Human SULT4A1 is 284 amino acids (aa) in length. A weak PAPS binding site is found between aa 246-254. There are two potential isoforms, one that shows a 13 aa substitution for aa 248-284, and a second that contains a 48 aa substitution for aa 202-247. Full length human SULT4A1 is 98% aa identical to mouse SULT4A1.
