Fig. 4From: SNP55, a new functional polymorphism of MDM2-P2 promoter, contributes to allele-specific expression of MDM2 in endometrial cancersMDM2-P2 promoter contains a SNP which affects the binding affinity of transcription factors. a Schematic illustration of the MDM2-P2 promoter. Single nucleotide polymorphism (SNP) 55 is upstream of SNP309 and two p53 responsive elements. b SNP55 alters transcription factors that can bind to DNA around SNP55 (analyzed by Alibaba 2.1)Back to article page
