(A) Experimental flow chart.
(B) Immunoblot showing the knockdown (KD) of Rbfox1 and Rbfox3 proteins in neurons incubated with Accell siRNAs targeting Rbfox1 (siRF1) and Rbfox3 (siRF3). GAPDH is used as loading control.
(C) Histogram of up-regulated (Up) and down-regulated (Dn) exons in KD experiments.
(D) Histogram of up-regulated (Up) and down-regulated (Dn) gene in KD experiments.
(E) Histogram of percentage of genes that contain ≥1 UGCAUG motif conserved in the 3′ UTR in human, mouse, rat, dog, and chicken genomes (UGCAUG_5G), ≥1 UGCAUG motif conserved in human and mouse genomes (UGCAUG_2G), or ≥1 GCAUG motif conserved in human and mouse genomes (GCAUG_2G). *** p < 10−15 by hypergeometric test.
