Analysis of the Ca2+ domain in the Arabidopsis H+/Ca2+ antiporters CAX1 and CAX3.

Plant molecular biology - 1 Oct 2002

Shigaki Toshiro, Sreevidya Coimbatore, Hirschi Kendal D

Abstract excerpt

Ca2+ levels in plants are controlled in part by H+/Ca2+ exchangers. Structure/function analysis of the Arabidopsis H+/cation exchanger, CAX1, revealed that a nine amino acid region (87-95) is involved in CAX1-mediated Ca2+ specificity. CAX3 is 77% identical (93% similar) to CAX1, and when expressed in yeast, localizes to the vacuole but does not suppress yeast mutants defective in vacuolar Ca2+ transport....
