Figure S4. TP53BP2 transcript analysis. (A) The UCSC genome browser (http://genome.ucsc.edu) was used to visualize the genomic positioning and organization of TP53BP2, which is located on chromosome 1q41. The genomic region spanning approximately 60 kb is displayed, and gene transcripts are shown in the tracks below the genomic regions. Additionally, the percentages of CpG islands and GCs are shown in the region below the gene transcript. (B) The Meth primer program identified one CpG island of 1240 bp (-599/+641 bp) at the TP53BP2 promoter. The red arrow indicates the transcription start site. The lower limits were as follows: %GC=50, obsCpG/exp CpG=0.60, and length=200 bp. CpG island star=1419, end=2634, %GC=74.4, obsCpG/expCpG=0.944.
