14-3-3 in Plants
Presence of large gene families of 14-3-3 proteins in the Viridiplantae kingdom reflects their essential role in plant physiology. A phylogenetic analysis of 27 plant species clustered the 14-3-3 proteins into four groups.
14-3-3 proteins activate the auto-inhibited plasma membrane P-type H+ ATPases. They bind the ATPases' C-terminus at a conserved threonine.

Famous quotes containing the word plants:
“What I did not yet know so intensely was the hatred of the white American for the black, a hatred so deep that I wonder if every white man in this country, when he plants a tree, doesn’t see Negroes hanging from its branches.”
—Jean Genet (1910–1986)
