a Exon/intron organization of spiH_vCNs in the genome of S. pistillata. Exons are represented as boxes, whereas introns are depicted as lines. b Sequence comparison of S. pistillata and H. sapiens H_vCN proteins. Identical and similar amino acids (aa) are shaded in black and grey, respectively, whereas aa that are missing from the other sequence are denoted by dashes. The boxes represent the predicted transmembrane segments in human H_vCN1 (S1-S4). The circles and crosses represent phosphorylation and N-glycosylation sites, respectively, in spiH_vCN1.1 and spiH_vCN1.2
