Gene Details:

• MSU gene ID: LOC_Os05g43840
• RAPdb gene ID: Os05g0514200
• Gene Symbol: PK4 OsPK4 OsCIPK19
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsPK4 and OsPK7 proteins produced in Escherichia coli were able to phosphorylate themselves and myelin basic proteins, the reaction requiring magnesium and/or manganese ions.
• Diverse response of rice and maize genes encoding homologs of WPK4, an SNF1-related protein kinase from wheat, to light, nutrients, low temperature and cytokinins.
• The wheat gene WPK4 encodes a 56-kDa protein kinase that belongs to group 3 of the SNF1-related protein kinase family (SnRK3), and is up-regulated by light and cytokinins and down-regulated by sucrose.
• Transcripts of OsPK4 were detected in all tissues tested, and amounts were increased upon illumination, nutrient deprivation and treatment with cytokinins.
• Both OsPK1 and OsPK4 localized to the mitochondria and cytosol and were recruited to the mitochondria by OsPK3.
