How can I differentiate between post-translational modifications of At3g06310 using available antibodies?

Post-translational modification (PTM) analysis of At3g06310 requires specialized methodological approaches:

• Use of modification-specific antibodies (phospho-specific, acetylation-specific, etc.)

• Two-dimensional gel electrophoresis followed by western blotting to separate modified forms

• Immunoprecipitation with general At3g06310 antibody followed by mass spectrometry

• Pre-treatment of samples with specific enzymes (phosphatases, deacetylases) to confirm modification identity

• Comparison between stressed and non-stressed conditions to identify regulated modifications

The validation of PTM-specific antibodies is particularly critical and should include controls with mutated modification sites. Researchers should document shifts in molecular weight, isoelectric point, and differential reactivity with modification-specific antibodies under varying physiological conditions .

• Technical controls: loading controls, secondary antibody-only controls

• Biological controls: tissue specificity controls, developmental stage comparisons

• Quantitative controls: standard curves for quantitative applications

The implementation of these controls should be systematically documented and analyzed. For instance, signal quantification in western blots should include normalization to appropriate loading controls, and immunolocalization studies should include quantification of co-localization coefficients with known markers .

How should I design experiments to investigate At3g06310 protein-protein interactions?

Investigating At3g06310 protein-protein interactions requires a multi-faceted experimental design:
