UGT88A1 Antibody

Definition and Function of UGT88A1 Antibody

UGT88A1 Antibody refers to a laboratory reagent designed to detect and study the UDP-glycosyltransferase 88A1 (UGT88A1) enzyme, a glycosyltransferase first characterized in Arabidopsis thaliana. This enzyme catalyzes the transfer of glycosyl groups from UDP-sugars to acceptor molecules, playing critical roles in plant secondary metabolism, including flavonoid glycosylation and polysaccharide biosynthesis . The antibody is used in immunological assays (e.g., Western blot, immunoprecipitation) to analyze UGT88A1 expression, localization, and functional interactions in biological systems.

Research Applications and Key Findings

UGT88A1 Antibody enables investigations into UGT88A1’s roles in:

• Quercetin Derivative Synthesis: UGT88A1 converts quercetin into quercetin-4′-O-glucoside, a compound with anti-inflammatory and anticancer properties. Mutant variants (e.g., V18R) enhance enzymatic efficiency, demonstrating structural insights into substrate binding .

• Polysaccharide Production in Fungi: In Grifola frondosa, UGT88A1 regulates β-D-glucan synthesis, impacting cell wall integrity and stress responses. Overexpression increases polysaccharide yield and antioxidant activity, while silencing reduces biomass production .
