Cloning, tissue and ontogenetic expression of the taurine transporter 1321 Fig. 1 Nucleotide and predicted amino acid sequences for S. senegalensis taurine transporter (TauT). Numbers on the left refer to nucleotide (upper row) and amino acid (lower row) positions. Nucleotide numbering starts on the initiation codon (ﬁrst ATG), while asterisk indicates the stop codon (TGA). Predicted alternating exons are represented by white and grey colors. Signature for the sodium/chloride-dependent neurotransmitter transporter superfamily is provided by an eight element ﬁngerprint (underlined from I to VIII). Signature for neurotransmitter symporter family is provided by a two element ﬁngerprint represented by white boxes, while signature for taurine transporters is provided by a four element ﬁngerprint (double underlined from 1 to 4) 123
