| Targets |
Sialic acid substrates and glycoprotein/glycolipid acceptors. alpha-2,6-Sialyltransferase (Pd26ST) catalyzes the transfer of sialic acid from CMP-sialic acid to galactose residues of glycoproteins and glycolipids, forming α-2,6-sialyl linkages. Sialyltransferases are glycosyltransferases that play critical roles in the biosynthesis of sialylated glycoconjugates. Sialic acids on cell surfaces are involved in cellular recognition, signaling, and immune modulation. The enzyme's activity is dependent on its substrates CMP-sialic acid and appropriate acceptor molecules.

| Enzyme Assay |
Non-cell-based assays for alpha-2,6-sialyltransferase involve measuring enzyme activity using purified enzyme and substrates. The enzyme is incubated with CMP-sialic acid and an acceptor substrate (e.g., asialofetuin, or synthetic substrates). The transfer of sialic acid is measured using radiolabeled CMP-sialic acid or by detecting the formation of sialylated products by HPLC or mass spectrometry. Enzyme kinetics (Km, Vmax) can be determined by varying substrate concentrations.
|
| Cell Assay |
Cell-based assays for alpha-2,6-sialyltransferase use various cell lines to study sialylation. Cells are cultured, and the expression and activity of the enzyme are assessed by measuring cell surface sialylation using lectin binding (e.g., Sambucus nigra agglutinin, SNA) or by detecting sialylated glycoproteins by Western blot. The effects of inhibitors or modulators on sialyltransferase activity can be studied. Gene expression is analyzed by qPCR.
|
| Animal Protocol |
In vivo studies of alpha-2,6-sialyltransferase are conducted in animal models to study the role of sialylation in physiology and disease. Knockout or transgenic mouse models may be used to study the effects of altered sialyltransferase expression on development, immune function, and disease susceptibility. Tissue samples are analyzed for sialylation patterns using lectin histochemistry or mass spectrometry.
