Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT1G18080 RACK1A abscisic acid Encodes the Arabidopsis thaliana homolog of the tobacco WD-40 repeat ArcA gene.
AT1G48630 RACK1B abscisic acid Encodes a protein with similarity to mammalian RACKs. RACKs function to shuttle activated protein kinase C to different subcellular sites and may also function as a scaffold through physical interactions with other proteins. RACK1B has no phenotype on its own and probably acts redundantly with RACK1A and RACK1C.
