Exon/intron structure of texim genes in the platyfish genome. The SGNH hydrolase domain(-coding region) is marked in light blue. Introns are represented by broken lines. Predicted start codons are in green and stop codons in red. cDNA and predicted protein sizes are provided. Helitron transposon positions are indicated. Question marks indicate lack of information due to absence of sequence data. Both coding and protein sequences of texim4 are partial.
