The KAT1 antibody is a crucial tool in plant biology research, specifically targeting the KAT1 protein—a potassium channel belonging to the Shaker family in *Arabidopsis thaliana*. First identified in the 1990s, KAT1 functions as an inward-rectifying potassium channel predominantly expressed in guard cells, where it regulates stomatal movements by modulating ion flux in response to environmental cues like light, CO₂, and abscisic acid (ABA). This channel plays a pivotal role in maintaining plant water balance and stress adaptation.
The KAT1 antibody, typically generated in rabbits or mice using immunogenic peptide sequences or recombinant protein fragments, enables researchers to investigate KAT1's expression, localization, and regulatory mechanisms. It is widely employed in techniques such as Western blotting, immunohistochemistry, and immunofluorescence to study protein abundance under varying physiological conditions (e.g., drought, salinity) or in mutant plants. Studies using this antibody have revealed KAT1's interaction with signaling components like kinases and phosphatases, as well as its post-translational modifications.
As stomatal regulation is central to photosynthesis and stress resilience, the KAT1 antibody has become instrumental in advancing research on crop improvement and climate adaptation strategies. Its applications extend to comparative studies of potassium channel evolution across plant species.
