Gene Details:

• Gene ID: Zm00001eb079410
• Gene Symbol: ZmPIMT2
• Gene Name: protein-L-isoaspartate methyltransferase2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• The YFP signal in NZmPIMT2:YFP expression vector-transformed protoplasts exhibited a similar subcellular pattern as seen with the ZmPIMT2:YFP expression vector , suggesting that the N-terminus of ZmPIMT2 is essential for the mitochondrial and chloroplast localization of ZmPIMT2.
• Overexpression of ZmPIMT2 in maize and Arabidopsis thaliana increased seed vigor upon artificial aging.
• ZmPIMT2 positively affects maize seed vigor.
• ZmPIMT2 binds ZmMCCα in mitochondria, repairs isoAsp damage, and positively affects maize seed vigor.
• ZmPIMT2 is specifically expressed in the maize embryo. Both mRNA and protein levels of ZmPIMT2 increased during seed maturation and declined during imbibition.
• ZmPIMT2 binding to ZmMCCα was confirmed by luciferase complementation tests in both tobacco (Nicotiana benthamiana) leaves and maize protoplasts.
• The N-terminus of ZmPIMT2 is essential for its mitochondrial localization and function.
