DOF1.8 Antibody

What is DOF1.8 and why is it significant in plant research?

DOF1.8 (AT1G64620) is a member of the plant-specific DOF (DNA-binding with One Finger) transcription factor family. DOF transcription factors regulate various physiological processes, including nitrogen assimilation, carbon metabolism, and response to biotic and abiotic stresses. DOF factors typically bind to the 5′-T/AAAAG-3′ core sequences in gene promoters, as demonstrated in studies with other DOF family members . The DOF1.8 antibody enables researchers to detect, quantify, and study the localization and interactions of this protein in plant tissues, providing insights into its functional role in plant development and stress responses. Unlike many other transcription factors, DOF proteins are plant-specific, making them particularly interesting for understanding unique aspects of plant regulatory networks and potential targets for crop improvement .

What experimental techniques can be used to detect DOF1.8 protein expression?

Several techniques can be employed to detect and characterize DOF1.8 protein expression:

• Western Blotting: This technique uses DOF1.8 antibody to detect the protein in plant tissue extracts following SDS-PAGE separation. The antibody is typically used at dilutions between 1:1000-1:5000, and detection can be performed using chemiluminescent or fluorescent methods . Protein extraction should be performed using appropriate buffers containing protease inhibitors to prevent degradation during sample preparation .

• Reverse Transcription-Polymerase Chain Reaction (RT-PCR): While this technique detects mRNA rather than protein, it can be used in conjunction with protein detection methods to correlate transcript and protein levels. Total RNA is extracted from plant tissues using kits such as the Plant Total RNA Extraction Kit, followed by cDNA synthesis and PCR with DOF-specific primers .

• Immunohistochemistry: This method enables visualization of the spatial distribution of DOF1.8 in different plant tissues and subcellular compartments using the specific antibody and appropriate detection systems.

• Enzyme-Linked Immunosorbent Assay (ELISA): Commercially available DOF1.8 antibodies are validated for ELISA applications, allowing quantitative analysis of protein levels across different samples .

• Immunoprecipitation: DOF1.8 antibody can be used to isolate the protein from complex mixtures for further analysis or to study protein-protein interactions through co-immunoprecipitation approaches .

How does DOF1.8 differ from other members of the DOF transcription factor family?

DOF1.8 shares the characteristic DOF domain with other family members but has unique features that distinguish it:

• Sequence Characteristics: While all DOF proteins contain a conserved zinc finger domain, DOF1.8 has specific sequence variations outside this domain that contribute to its unique function. The DOF1.8 antibody (Gene Symbol: AT1G64620, UniProt Number: Q84JQ8) specifically recognizes this protein based on these unique regions .

• Functional Specialization: Unlike DOF1 which has been implicated primarily in nitrogen assimilation and carbon metabolism , or OsDes1 which contributes to stay-green phenotypes and disease resistance in rice , DOF1.8 may have evolved specialized functions in Arabidopsis.

• Expression Patterns: DOF proteins often show tissue-specific or condition-specific expression patterns that contribute to their specialized roles. Studying these patterns using DOF1.8 antibody can reveal insights into its unique biological functions.

• Target Gene Specificity: While all DOF proteins bind to similar core sequences (5′-T/AAAAG-3′), differences in the regions flanking the DOF domain can confer specificity for different target genes, resulting in distinct physiological roles .
