The nucleotide sequence of mouse Sox5 (mSox5) cDNA derived from the testis has been reported by Denny et al. (EMBO J. 11 (1992) 3705-3712). We newly isolated an mSox5 cDNA derived from 8.5-day mouse embryo. Our cDNA encodes a protein of 763 amino acids, which is considerably larger in size than the previous one (392 amino acids) derived from the adult mouse testis. The most significant difference between the embryo-derived and testis- derived mSox5 cDNAs is that the embryonic one encodes a leucine zipper motif and a neighboring glutamine-rich sequence stretch (named Q box), but the testis-derived one does not. The leucine zipper and the Q box are highly conserved among type-D SOX proteins including mSox5. mSox5 was suggested to be a single-copy gene by Southern analysis. With reverse transcription/polymerase chain reaction, we found that not only mouse embryo, but also the adult mouse testis, express mSox5 mRNA species encoding the leucine zipper and the Q box.
