HXK7 Antibody

What is HXK7 Antibody and what biological system does it target?

HXK7 Antibody is a polyclonal antibody that specifically targets Hexokinase-7 (HXK7), a crucial enzyme in plants, particularly in Oryza sativa subsp. japonica (Rice). The antibody recognizes and binds to either recombinant or native HXK7 protein, which plays a fundamental role in sugar metabolism by catalyzing the phosphorylation of glucose to glucose-6-phosphate, the first step in the glycolytic pathway .

Commercially available HXK7 antibodies are typically rabbit-derived polyclonal antibodies generated against recombinant Oryza sativa HXK7 protein. These antibodies are provided in liquid form, typically stored in a preservation buffer containing 50% glycerol, 0.01M PBS at pH 7.4, and 0.03% Proclin 300 to maintain stability and activity .

What is the molecular function of the HXK7 target protein?

HXK7 (Hexokinase-7) is a key enzyme responsible for phosphorylating fructose and glucose as the critical first step in sugar metabolism. Beyond its catalytic function, research has revealed that rice hexokinase OsHXK7 demonstrates moonlighting properties, serving a dual role in both sugar signaling and metabolism .

The enzyme plays a particularly crucial role in rice germination, especially under oxygen-deficient conditions. Studies have indicated that OsHXK7 promotes glycolysis-mediated fermentation during germination in oxygen-limited environments, making it essential for efficient germination in rice . This dual functionality as both a metabolic enzyme and signaling molecule makes HXK7 an important target for research on plant energy regulation and stress responses.

What are the primary applications of HXK7 Antibody in scientific research?

HXK7 Antibody has several important applications in plant biology research:

The antibody has been particularly valuable in research exploring sugar metabolism, plant energy regulation, and stress responses in rice . Its applications extend to studies examining how HXK7 functions in both metabolic processes and signaling pathways, providing insights into the complex regulatory networks governing plant growth and development.

What are the recommended protocols for using HXK7 Antibody in Western blotting?

A detailed Western blotting protocol for HXK7 Antibody should include the following key steps:

• Sample Preparation:

  • Extract total protein from rice tissues using an appropriate lysis buffer (e.g., 50 mM Tris-HCl pH 7.5, 150 mM NaCl, 1% Triton X-100, 1 mM EDTA, with protease inhibitors)

  • Determine protein concentration using Bradford or BCA assay

  • Mix samples with Laemmli buffer containing β-mercaptoethanol
