Figure 1From: Renal kallikrein excretion and epigenetics in human acute kidney injury: Expression, mechanisms and consequences Map of CpG sites studied in the human KLK1 proximal promoter. Letters highlighted in gray are the target regions complementary to amplified PCR primers. The CpGs analyzed are numbered as Pos#1 - Pos#4 and colored yellow. Green underlined sequences are target regions complementary to sequencing primers. Green highlighted A is the transcriptional initiation ("cap") site. Sequences following the transcription initiation site are colored pink.Back to article page
