• Information
  • Symbol: OsCBK
  • MSU: LOC_Os03g25070
  • RAPdb: Os03g0366200
• Publication
  • Calmodulin isoform-specific activation of a rice calmodulin-binding kinase conferred by only three amino-acids of OsCaM61, 2006, FEBS Lett.
  • Molecular and biochemical characterization of a calcium/calmodulin-binding protein kinase from rice, 2002, Biochem J.
• Genbank accession number
  • AF368282
• Key message
  • OsCBK is highly expressed in zones of cell division and it is particularly abundant in sporogenous cells of the anther at meiosis
  • In situ hybridization showed that OsCBK is expressed in reproductive and vegetative tissues of rice and shows temporal and spatial changes during plant growth and development
• Connection
  • OsCaM61, OsCBK, Calmodulin isoform-specific activation of a rice calmodulin-binding kinase conferred by only three amino-acids of OsCaM61, It was observed that OsCaM61 stimulated OsCBK in a Ca(2+)-dependent manner
  • OsCaM61, OsCBK, Calmodulin isoform-specific activation of a rice calmodulin-binding kinase conferred by only three amino-acids of OsCaM61, Mutational study and fluorescent spectroscopy analysis indicated that CaM-binding affinity does not correlate with the kinase activity and that these key amino-acids in OsCaM61 play a vital role in suitable changes of OsCBK conformation for kinase activation
