Abstract:

This experiment was conducted to screen the transcription factor binding sites of MyoDI promoter in Guizhou Guanling cattle.According to the sequence of bovine MyoDI gene published in GenBank,the specific primer was designed to amplify the promoter region of MyoDI gene in Guanling cattle.The PCR products was used to construct the recombinant cloning vector pUCM-T-MyoDI-pro.Positive plasmids were authenticated by sequencing.Then screening experiment and bioinformatics analysis were applied to screen the transcription factor binding sites of MyoDI promoter in Guanling cattle.The results showed that the transcription factor binding sites of MyoDI promoter in Guizhou Guanling cattle had SATB1,Xbp,MEF2,Pax-3,Pbx1,PPAR,TFⅡD,COUP-TF,Gfi-1,HNF-1,HOX4C,NRF2(ARE),MEF1,RXR,SMUC,Snail,MyoD and VDR.Combined with online software analysis and literature,we ultimately screened out the MyoD,TFIID,Pax3,MEF1,VDR and MEF2 in MyoDI promoter.These transcription factors play an important role in regulation of promoter activity.The result indicate that the Guanling cattle MyoDI promoter contain MyoD,TFIID,Pax3,MEF1,VDR and MEF2 transcription factor binding sites.
