| Primary Identifier | IPR044300 | Type | Family |
| Short Name | STOP1/2 |
| 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 []. |
