Figure 3.

N-terminal regions of Syts Syts are identified on the left. Mus and Homo Syts are are bracketed and named. Arabidopsis Syts are named following the nomenclature of Fukuda [14]. Amino acid sequence length is indicated on top. Putative transmembrane regions are indicated with a yellow background. Intron positions are indicated by red vertical lines. Regions of alternative splicing or RNA editing are enclosed by red boxes. The main branches of Syts are separated by horizontal blue lines. Similarity between members of a main branch is indicated with a coloured background. A motif common to Syt 15, Syt9, Syt10, Syt6 and Syt3 is indicated in blue in fig. 4.
