In planta regulation of the Arabidopsis Ca(2+)/H(+) antiporter CAX1.
Vacuolar localized Ca(2+)/H(+) exchangers such as Arabidopsis thaliana cation exchanger 1 (CAX1) play important roles in Ca(2+) homeostasis. When expressed in yeast, CAX1 is regulated via an N-terminal autoinhibitory domain. In yeast expression assays, a 36 amino acid N-terminal truncation of CAX1, termed sCAX1, and variants with specific mutations in this N-terminus, show CAX1-mediated Ca(2+)/...
متن کاملRegulation of CAX1, an Arabidopsis Ca /H Antiporter. Identification of an N-Terminal Autoinhibitory Domain
Regulation of Ca transport determines the duration of a Ca signal, and hence, the nature of the biological response. Ca /H antiporters such as CAX1 (cation exchanger 1), play a key role in determining cytosolic Ca levels. Analysis of a full-length CAX1 clone suggested that the CAX1 open reading frame contains an additional 36 amino acids at the N terminus that were not found in the original clo...

متن کاملRole of the AtClC genes in regulation of root elongation in Arabidopsis
The protein family of anion channel (ClC) constitute a family of transmembrane trnsporters that either function as anion channel or as H+/anion exchanger. The expression of three genes of AtClCa, AtClCb and AtClCd in the model plant Arabidopsis thaliana were silenced by a T-DNA insertion . When the pH of the medium was slightly acidic the length of the primary root of plants with a disrupted At...
