摘要 根据p53下游基因在其调节区域(启动子或内含子)含有与P53蛋白特异性结合的一致性序列5’?RRRCWWGYYYN(0-13)RRRCWWGYYY-3’,R=G或A,W=T或A,Y=C或T,N=A,C,T,G。用计算机对人类基因组中P53结合位点进行了研究,发现Y染色体上的TSPY1基因内含子中含有这样的一致性序列5’-GGGCTAGTTTtgGAGCTAGCCT-3’,意味着TSPY1基因有可能是一个p53下游基因。 It's known that p53 downstream genes in the regulatory region(promoter or intron) contain p53 consensus binding sequence, 5" RRRCWWGYYYN (0 - 13) RRRCWWGYYY-3 ', R = G or A,W=T or A,Y=C or T,N=A,C,T,G. The authors analyse DNA binding sequence for wild-type P53 in human genome by Computational method and discover that there is a consensus sequence,5'-GGGCTAGTTTtgGAGCTAGCCT-3' ,in intron 2 of the TSPYl(testis specific protein, Y-linked 1) genes in hunan chromosome Y. It suggests that TSPY1 gene may be a p53 downstream gene.
