Enrichment in DNA-binding motifs within BL-CFC Ldb1 binding peaks. (A) Most prevalent motifs enriched within Ldb1-binding peaks of Set1. (B) Most prevalent motifs enriched within Ldb1-binding peaks of Set2. Frequency of each motif within the total number of studied binding peaks is given. (C) Each identified motif has been associated with one or more transcription factors found in the JASPAR database, and the significance of this association is determined by the P value. Each factor represents a family of transcription factors binding the same motif.
