DESCRIPTION:There are eight annexin genes in the model species Arabidopsis
  thaliana.  Annexins are thought to have diverse roles ranging from hydrol
 ysis of ATP and GTP\, cation channel formation and regulation\, to exocyto
 sis and cell cycle control. Plant annexins are able to bind intracellular 
 calcium with an endonexin fold within a five α helical annexin repeat and
  have been discovered in a number of cellular compartments in various spec
 ies and tissues. A. thaliana Annexin 1 (ANNAt1) is highly expressed in the
  roots and increases in expression levels of ANNAt1 have been recorded in 
 response to drought\, salinity\, cold\, heat and heavy metal stress. To da
 te ANNAt1 has been experimentally shown to function as a plasma membrane c
 alcium and potassium conductive protein\, activated by hydroxyl radicals (
 in lipid bilayers) and salt stress (epidermal protoplasts) implicating the
  protein in sodicity signalling. Reactive oxygen species activated calcium
  channels also function in growth\, indicating ANNAt1 may function in this
  essential pathway.
