Fig. 1From: Promoter methylation inhibits expression of tumor suppressor KIBRA in human clear cell renal cell carcinomaCpG islands within KIBRA promoter P1a and P1b. The alternative KIBRA promoter system composed of promoter regions P1a, P1b, P2, and P3 and their respective transcription start sites (TSS; right-angled arrows; filled boxes represent exons) located on chromosome 5. Two CpG islands with a length of 205 bp (CpG II, position − 3594/− 3799) and 764 bp (CpG I, position − 1/− 764) within the KIBRA promoter regions P1a and P1b were identified. Of note, Figure S1 contains detailed description of CG dinucleotide rate and positions within CpG islandsBack to article page
