From: Genomic organisation and alternative splicing of mouse and human thioredoxin reductase 1 genes

Alignment of mouse thioredoxin reductase 1 (Txnrd1) exon 3b with partial human thioredoxin reductase 1 (TXNRD1) genomic DNA sequence. Splice junctions (AG/GT) are outlined in TXNRD1. The ATG codon that yields the 67 kDa protein form is conserved in both genes and is boxed.
