PAR-CLIP data from Kishore et al. and Mukherjee et al. were analyzed for binding sites of HuR in FMR1

Study	Assay	CLIP tag FMR1 3′UTR coordinate
Kishore et al. (44)	PAR-CLIP_Protocol 1	c.*726–c.*765
Kishore et al. (44)	PAR-CLIP_Protocol 2	c.*727–c.*766
Mukherjee et al. (43)	PAR-CLIP	c.*679–c.*710
Lebedeva et al. (42)	PAR-CLIP	c.*977–c.*1002

From Kishore et al., protocol 1 used micrococcal nuclease to digest PAR-CLIP mRNA libraries and was performed in duplicate. Protocol 2 used RNase T1 to digest PAR-CLIP mRNA libraries and was performed once.
