Analysis of RRP1B-binding regions detected through ChIP-seq. Regions bound by endogenous RRP1B in MDA-MB-231 and HeLa cells were defined with MACS. Genomic sequences were partitioned into four bins relative to RefSeq genes; distal promoter, proximal promoter, downstream, and genic. The genic bin was further divided by 5′ UTR, exons, introns, and 3′ UTR. The number of peaks for each bin is shown here

Peak Position Relative to Gene		HeLa	MDA-MB-231
Distal promoter		150	64
Proximal promoter		156	54
Downstream		263	102
Genic		205	90
Genic	5′ UTR	61	21
	Exons	60	13
	Introns	129	74
	3′ UTR	33	19
