Abstract: Total RNA from Landes goose liver of 16 weeks old was extracted.The cDNA segment about 282 bp of Langdes goose was amplified by the reverse transcription-polymerase chain reaction(RT-PCR)Sequence analysis showed that there is a high similarity between the fragment of cDNA and sterol regulatory element binding protein-1(SREBP-1) gene containing a bHLH function region. Meanwhile, the segment evidently has a hydrophilic region and a hydrophobic region, and the secondary structure richly contains αhelix, which accords with its function.
