Gene structures for all known and putative genes. Coordinates are placed according to the forward sense of BAC sequence (AF220294). All exons identified are shown as boxes. Alternative exon splicing likely occurs with Igfals, Tce1, D17Wsu15e (Jsap1), and D17Ertd441e. Tce2 has complete connecting EST coverage and is likely a complete gene structure. The remaining unknown genes are likely to be incomplete gene structures. Splice variants are not distinguished in the above diagram. Exons and distances between exons are drawn to scale, unless indicated otherwise by dashed or broken lines. An arrow under the gene name indicates the expected direction of transcription. Additional features are indicated by an asterisk (*), no splice site identified; filled bar, open reading frame; open bar, no open reading frame; dashed open bar, exon not drawn to scale; dashed line, distance not to scale.
