Function
SLAH3_ARATH Slow, weak voltage-dependent S-type anion efflux channel involved in maintenance of anion homeostasis (PubMed:18305482). Binds to the highly selective inward-rectifying potassium channel KAT1 and inhibits its activity. Functions as an essential negative regulator of inward potassium channels in guard cells. Essential for the efficient stomatal closure and opening in guard cells (PubMed:27002025).[1] [2]
