NCBI Protein Information
C2H2 and C2HC zinc fingers superfamily protein
NCBI Summary
Encodes a putative nuclear Cys(2)His(2)-type zinc finger protein involved in H+ and Al3+ rhizotoxicity. In mutants exposed to aluminum stress, there is no induction of AtALMT1, an malate transporter known to be involved in the mediation of aluminum toxicity. Cell wall of the mutant is unstable in low pH medium (pH 4.5) in low Ca solution. This would mediate Ca-alleviation of low pH stress through pectin-Ca interaction.

UniProt Comments
Probable transcription factor. Together with STOP2, plays a critical role in tolerance to major stress factors in acid soils such as proton H+ and aluminum ion Al3+. Required for the expression of genes in response to acidic stress (e.g. ALMT1 and MATE), and Al-activated citrate exudation.
