Expression of Zfhx2 mRNA in an E15.5 mouse brain. This gene is highly expressed also in dorsal root ganglion.

 

ZFHX2 is a nociceptor-expressed transcription factor containing 3 homeobox domains and 18 zinc-finger motifs. Depositor (Dr. Yamamori) and his colleague achieved cloning of Zfhx2 and developed Zfhx2-global knockout mice in 2006 (1). Zfhx2 expression is observed highly in the developing brain and Zfhx2-global knockout mice show several behavioral abnormalities (2).

Recently, it was reported that Marsili syndrome (OMIM: 147430) is caused by a point mutation in ZFHX2 gene (3). The Marsili syndrome is a human Mendelian disorder and the symptom is insensitivity to pain. Zfhx2-global knockout mice also show the unusual pain perception phenotype.

Zfhx2-global knockout mice are useful for elucidation of pain-related molecular network. Therefore, this strain will contribute to development of novel analgesic drugs in future.
