WebWe explored the mechanisms of RBFOX splicing activation and repression using an MS2-tethering assay. We found that the Ala/Tyr/Gly-rich C-terminal domain is sufficient for exon activation when tethered to the downstream intron, whereas both the C-terminal domain and the central RRM are required for exon repression when tethered to the upstream intron. http://www.redfoxmobile.com.au/

WebSep 11, 2024 · Rbfox family proteins contain two critical phenylalanine (F) residues within the RRM domains (amino-acids 108 and 142 in Rbfox3) that are required for RNA-binding activities. The F142 mutation to alanine (F142A) in Rbfox3 abrogates its binding activity to both the canonical binding motif UGCAUG and noncanonical target RNAs.
WebIt is reported here that sequence-specific binding of the conserved Rbfox RRM to miRNA precursors containing the same sequence motif in their terminal loops, including miR-20b and miR -107, suppresses their nuclear processing.
