Protein Domain : Protein SENSITIVE TO PROTON RHIZOTOXICITY 1/2 IPR044300

Type  Family
Description  This entry represents a group of plant zinc finger proteins, including STOP1/STOP2 from Arabidopsis and their homologues, Os01g0871200/STAR3 from rice. They are putative transcription factors that regulate gene expression associated with multiple stress tolerances in plant roots [ , , ]. STOP1 (sensitive to proton rhizotoxicity 1) regulates transcription of multiple genes critical for tolerance to aluminum (Al) and low pH in Arabidopsis []. STOP2 is a physiologically minor isoform of STOP1, but it can activate expression of some genes regulated by STOP1 []. In rice, ART1 regulates multiple genes implicated in aluminum tolerance [].
