The end of termination window precisely matches Pol II occupancy and co-localizes with termination factors. a, c Meta-profile of published ChIP-seq signal for Pol II, Ser2P, Ser5P [53] (a) and BDR1, FPA [54] (b) centered around either the poly(A) site (pA) or the termination window end (TWE). b Meta-profile of read coverage for FLEP-seq and pNET-seq [41] centered around the poly(A) site or the termination window end. d Meta-profiles of Pol II, Pol II Ser2P, BDR1, and FPA ChIP-seq signal in four groups of genes ordered by different termination window sizes. e Venn diagram shows the overlap between BDR1, FPA peaks, and termination windows
