S. Smith et al., Identification and analysis of two snail genes in the pufferfish (Fugu rubripes) and mapping of human SNA to 20q, GENE, 247(1-2), 2000, pp. 119-128
All members of the snail gene family are zinc-finger transcription factors
expressed early in embryonic development and are involved in the formation
of tissues such as mesoderm and presumptive neural crest. Here, we report t
he identification and structural organisation of two snail genes in the com
pact genome of the pufferfish Fugu rubripes, and examine the phylogenetic r
elationships between these and other members of the snail gene family. Both
genes have a three exon, two intron structure similar Lo that previously r
eported for human SLUG. While human SLUG has been mapped to 8q (Cohen, M.E.
, Yin, M., Paznekas, W.A., Schertzer, M., Wood, S., Jabs, E.W., 1998. Human
SLUG organisation, expression and chromosome map location on 8q. Genomics
51, 468-471), the human sna gene SNA, was previously unmapped. We have used
sequence similarity to the Fugu genes to identify a human SNA EST and mapp
ed this by radiation hybrid and physical mapping to the distal end of human
20q. This is likely to be the mapping location of the human sna gene (SNA)
