NCBI Summary
Encodes a potassium channel protein (KAT1). ABA triggers KAT1 endocytosis both in epidermal cells as well as guard cells. Upon removal of ABA, KAT1 is recycled back to the plasma membrane. KAT1 is localized within 0.5?0.6 mum diameter microdomains at the plasma membrane surface. KAT1 belongs to the Shaker family K+ channel. This family includes five groups based on phylogenetic analysis (FEBS Letters (2007) 581: 2357): I (inward rectifying channel): AKT1 (AT2G26650), AKT5 (AT4G32500) and SPIK (also known as AKT6, AT2G25600); II (inward rectifying channel): KAT1 (AT5G46240) and KAT2 (AT4G18290); III (weakly inward rectifying channel): AKT2 (AT4G22200); IV (regulatory subunit involved in inwardly rectifying conductance formation): KAT3 (also known as AtKC1, AT4G32650); V (outward rectifying channel): SKOR (AT3G02850) and GORK (AT5G37500).

UniProt Comments
Highly selective inward-rectifying potassium channel. This voltage-gated channel could mediate long-term potassium influx into guard cells leading to stomatal opening. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by hyperpolarization. The channel activity is enhanced upon external acidification. Also permeable to ammonium ions. Blocked by tetraethylammonium and barium ions.
