From: Nuclear Receptor HNF4α Binding Sequences are Widespread in Alu Repeats
The vast majority of HNF4α binding sites in the human genome are found in Alu repeats. A. Numerical results from PBM3 described in Fig. 1 and in the text. B. Position weight matrices (PWMs) generated with Weblogo [76] of sequences bound by human HNF4α2 in the PBM, categorized by the type of sequence. The DR1-derived PWM was from 994 sequences bound by HNF4α2, the DR2-derived PWM from 50 sequences and the Alu-derived sequences from 66 sequences. The non canonical PWM is from Bolotin et al. [42].
