Calreticulin and calnexin in plants

It has been proposed that the two closely related proteins calreticulin and calnexin may act as molecular chaperones. However, calreticulin has also been implicated in a wide variety of seemingly unrelated cellular processes, which has led to considerable controversy about its function. There have been a number of recent reports on the specific properties of calreticulin and calnexin in plants. Although many of these observations may well be related to their suggested functions in other eukaryotic systems, it is likely that the plant homologs also have unique features.
