SNAREs are membrane-associated proteins that play a central role in vesicle targeting and intra-cellular membrane fusion reactions in eukaryotic cells. Here we describe the identification of AtBS14a and AtBS14b, putative SNAREs from Arabidopsis thaliana that share 60% amino acid sequence identity. Both AtBS14a and BS14b are dosage suppressors of the temperature-sensitive growth defect in sft1-1 cells and over-expression of either AtBS14a or AtBS14b can support the growth of sft1Δ cells but not bet1Δ cells. These data together with structure-function and biochemical studies presented herein suggest that AtBS14a and AtBS14b share properties that are consistent with them being members of the Bet1/Sft1 SNARE protein family.
