The 14-3-3 proteins comprise a family of highly conserved proteins with multiple functions, most of which are related to signal transduction. Four isoforms from the plant Arabidopsis thaliana were able to complement the lethal disruption of the two Saccharomyces cerevisiae genes encoding 14-3-3 proteins; one complemented very poorly and one did not complement. However, the expression of the latter two isoforms was very low. These results show that at least four of the six A. thaliana isoforms are able to perform the same function(s) as the yeast 14-3-3 proteins.
