Context pattern of AuxRE
revealed by sequence analysis of experimentally proven AuxREs. oPWM  provided for mono- (A.) and dinucleotide PWMs (B.). Logos for PWMs were computed according to . C. SiteGA  revealed significant correlations between the frequencies of locally positioned dinucleotides. The average counts of significant dependencies are shown on the Y axis per positions along AuxRE site (X axis). AuxRE core TGTCNN locates in [-3;+3] nt. D - F. Logos for potential coupling elements found on the flanks of experimentally proven AuxREs. D. ABRE-like. E. Y-patch. F. AuxRE-like.
