The mutation was generated using zinc finger nuclease technology. The mutation involves insertion of one extra C at position 16:20486368 in the intronless JunD gene (Rat (Rnor_6.0)Ensembl) resulting in a null mutation.
Jund is a member of the JUN family, and a functional component of the AP1 transcription factor complex. Diseases associated with JUND include human t-cell leukemia virus type 1 and breast cancer. Among its related pathways are MAPK signaling pathway and Akt Signaling.
