Q&A

What is DOF1.6 and what is its biological function?

DOF1.6 is a plant-specific transcription factor that belongs to the DOF (DNA-binding with One Finger) family. It binds specifically to a 5'-AA[AG]G-3' consensus core sequence in DNA. DOF proteins function as transcriptional regulators involved in multiple plant-specific biological processes including seed germination, photosynthesis, flowering, and response to phytohormones. DOF1.6 specifically has been implicated in the regulation of light-responsive genes and carbon metabolism in plants, making it a critical protein for understanding plant development and environmental responses.

In Arabidopsis thaliana, DOF1.6 is encoded by the AT1G47655 gene. The protein contains a highly conserved N-terminal DNA binding domain characterized by a C2-C2 zinc finger structure, which recognizes specific promoter elements in target genes. The C-terminal region contains transcriptional activation domains that interact with other transcription factors and regulatory proteins.

How does DOF1.6 antibody differ from other DOF family antibodies?

DOF1.6 antibody is designed to specifically recognize epitopes unique to the DOF1.6 protein, distinguishing it from other members of the DOF family. This specificity is crucial because the DOF family in plants comprises multiple members (over 30 in Arabidopsis and over 40 in rice) that share the highly conserved DOF domain but differ in their variable regions.

High-quality DOF1.6 antibodies are typically raised against synthetic peptides derived from unique regions of the DOF1.6 protein, particularly from the variable C-terminal region that shows less conservation among family members. This approach ensures minimal cross-reactivity with other DOF proteins. When selecting a DOF1.6 antibody, researchers should carefully review validation data demonstrating specificity through techniques such as Western blotting against recombinant DOF proteins and competitive blocking with the immunizing peptide .

What are the typical applications for DOF1.6 antibody in plant research?

DOF1.6 antibody can be employed in multiple experimental approaches:

  • Chromatin Immunoprecipitation (ChIP): To identify genomic regions bound by DOF1.6 in vivo, helping to map its direct target genes

  • Immunolocalization: To determine the subcellular localization of DOF1.6 protein in different plant tissues and developmental stages

  • Western Blotting: To quantify DOF1.6 protein levels in different tissues or under various experimental conditions

  • Co-Immunoprecipitation (Co-IP): To identify protein-protein interactions between DOF1.6 and other transcription factors or regulatory proteins

  • Immunohistochemistry (IHC): To visualize the spatial expression pattern of DOF1.6 in plant tissues

Each application requires specific antibody validation parameters, with ChIP-grade antibodies typically requiring the most stringent specificity and sensitivity testing.

What are the optimal conditions for Western blot detection of DOF1.6?

For optimal Western blot detection of DOF1.6, researchers should follow these methodological guidelines:

Sample Preparation:

  • Extract proteins from plant tissue using a buffer containing 50 mM Tris-HCl (pH 7.5), 150 mM NaCl, 1% Triton X-100, and protease inhibitor cocktail
