GOLIM4 and cancer: RBFOX2 is a well‐characterized pre‐mRNA splicing regulator and has been implicated in organ development and cancer progression.[21] Using in vivo CLIP and minigene reporter assays, we demonstrated that RBFOX2 could bind to the GGAA motif in GOLIM4 exon‐7 and mediate its alternative splicing of GOLIM4.
