Preferential KAT1-KAT2 heteromerization determines inward K+ current properties in Arabidopsis guard cells.

The Journal of biological chemistry - 26 Feb 2010

Abstract excerpt

Guard cells adjust their volume by changing their ion content due to intense fluxes that, for K(+), are believed to flow through inward or outward Shaker channels. Because Shaker channels can be homo- or heterotetramers and Arabidopsis guard cells express at least five genes encoding inward Shaker subunits, including the two major ones, KAT1 and KAT2, the molecular identity of inward Shaker channels operating...
