The PCR product (413 bp) was cloned and sequenced. The nucleotide sequence and the deduced amino acid sequence of a homeobox, which was isolated in this study, designated Gtx 2 were obtained. The result of sequence analysis showed that there is an intron between the nucleotides at position 138 and 139 in the Gtx 2 homeobox. Southern blot analysis revealed that Gtx 2 is likely to exist as a single copy in the murine genome. Comparison of the encoded polypeptide sequence with other homeodomains reveals that Gtx 2 has 96% and 58% identity to that of Gtx 1 and Tcl 3 , respectively.展开更多
