Origin:
This strain was identified in the N-ethyl-N-nitrosourea (ENU)-driven target-selected mutagenesis screen. A point mutation in the Slc6a3 (DAT) coding sequence (exon 3) with a T/G transversion at nucleotide position 471 was identified in a male rat. This nucleotide exchange leads to substitution of an asparagine amino acid residue by a lysine residue at position 157 (N157K) in the SLC6A3 (DAT) protein, which introduces new positive charge into the amino acid sequence.
