“…Cadherin-4 (Cdh4), also called R-cadherin, is a member of the type-I classical cadherin subfamily (Redies, 1995;Nollet et al, 2000). Cdh4 expression and/or function in the vertebrate nervous system has been studied in a variety of vertebrate species including zebrafish, Xenopus, chicken, and mouse (Inuzuka et al, 1991;Redies et al, 1992;Ganzler and Redies, 1995;Matsunami and Takeichi, 1995;Tashiro et al, 1995;Liu et al, 1999;Wohrn et al, 1998;Gerhardt et al, 2000;Honjo et al, 2000;Treubert-Zimmermann et al, 2002;Andrews and Mastick, 2003;Babb et al, 2005). We previously showed that Cdh4/cdh4 is expressed in the majority of the cranial and lateral line ganglia and their nerves in the developing zebrafish (Liu et al, 2003).…”
