New Gene Name for Nude Mice
JAX® Bulletin #6
May 25, 2000
Effective May 4, 2000, the gene nomenclature for nude mutant mice changed from Hfh11nu to Foxn1nu (see Table 1 below). The nomenclature was previously updated from nu to Hfh11nu, when the gene was cloned and identified as a mutation in the HNF-3/forkhead homolog 11 gene (Segre et al., 1995). Further research has delineated the structure of the HNF3 (hapatocyte nuclear factor 3) domain and identified the gene as a member of the Fox gene family (Kaestner et al., 2000).
Fox (forkhead box) has been adopted as the symbol for all winged helix/forkhead transcription factors characterized by a 100 amino acid DNA-binding domain. The FOX proteins have been assigned to subclasses based on phylogenetic analysis, with each subclass given a specific letter. Within each subclass, proteins are given a specific number.
Corresponding names follow the format of, "Fox, subclass N, member X". All gene symbols are italicized. For human nomenclature, all letters are capitalized (e.g., FOXN1), for mice, only the first letter is capitalized (e.g., Foxn1), and for all other species, the first letter and the subclass letters are capitalized (e.g., FoxN1).
