A family of SRY-related genes has been termed SOX. We have isolated and sequenced a cDNA encoding a novel Sox protein from Xenopus laevis ovary. This cDNA contains an open reading frame (ORF) coding for 362 amino acids, which encompasses an HMG box and exhibits a strong (90%) identity to that of mouse Sox7; the cDNA was named xSox7 in this study. Northern analysis revealed that the xSox7 mRNA was 2.0 kb in length. Various adult frog tissues were tested by reverse transcription/polymerase chain reaction for xSox7 mRNA, and the results showed that xSox7 is expressed in a wide range of tissues. Furthermore, electrophoretic mobility shift assay indicated that recombinant xSox7 is capable of binding to AACAAT sequence.
