Gene Details:

• Gene ID: Zm00001eb144450
• Gene Symbol: ZmKS ZmOST1 bhlh132
• Gene Name: bHLH-transcription factor 132
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• A maize ZmOST1 Kinase Substrate ZmKS, showing homology with basic helix-loop-helix (bHLH) DNA-binding transcription factor was identified.
• ZmKS is localized in the nucleus, shows a potential binding specificity preferentially detectable on cis-acting E-box like heptameric motifs CCACTTG and CAAGTTG, and is phosphorylated by maize protein kinase ZmOST1. ZmKS is expressed in embryo, leaf and root, expression being affected by ABA and osmotic stress.
• We isolated a ZmOST1- interacting cDNA encoded polypeptide. The analysis of the sequence indicated that this protein is a member of the basic helix-loop-helix (bHLH) superfamily, showing high homology with the Arabidopsis thaliana bHLH transcription factor AKS2 , which is a kinase substrate of AtOST1.
• ZmOST1 mediates abscisic acid regulation of guard cell ion channels and drought stress responses.
