In unTitle Loaded From File differentiated cells, Tead4 occupied 2940 internet sites positioned mainly distant from the transcription start off web-sites (TSS) (Fig 4A and S1 Dataset). In differentiated cells, much more than 8100 web-sites have been occupied, the majority of which have been once again situated distant in the TSS (Fig 4B and S1 Dataset). Occupied internet sites in each undifferentiated and differentiated cells showed robust enrichment of the MCAT motif (Fig 4C and 4D). Other motifs co-occurred with the MCAT motif at higher than anticipated frequency. In undifferentiated cells, enrichment in motifs for the AP1 (Fos and Jun) family was observed along with Runx1 that cooperates with AP1 and Myod1 to drive myoblast proliferation in the course of muscle regeneration [23] (Fig 4C). In differentiated cells, AP1 and Runx motifs had been enriched, but further motifs became prominent including Ctcf, and Tcf3 plus the E-Box (Fig 4D).PLOS Genetics | DOI:10.1371/journal.pgen.1006600 February 8,five /Tead4 drives myogenic differentiationFig 2.

Outcomes of MEME analysis around the prime 600 Tead4 occupied internet sites in non-differentiated and differentiated C2C12 cells. Reduced panels indicate the frequency of occurrence of DNA binding motifs for the indicated transcription components at Tead4 occupied web sites in undifferentiated and differentiated C2C12 cells comparing the anticipated values with all the observed values.
