Annotation of the bovine and human FNDC5 genes.

<p>(<b>A</b>) Bovine FNDC5 locus as annotated in the current build of the bovine genome (UMD 3.1). (<b>B</b>) Structure of the human FNDC5 locus. (<b>C</b>) Annotated transcripts of the human FNDC5 gene (GenBank accession numbers NM_001171941.1, NM_153756.2, NM_001171940.1). Boxes denote exons with putative coding regions in black. Exon numbers are given below the boxes with lengths in base pairs. Intron lengths are given above the line. Dashed boxes indicate parts of exons which may encode amino acids when the alternative start codon in the human gene is used. The nucleotide numbers of the genomic sequences are given above the arrows.
