Function Description | In breast cancer cells,IMP1 interacts with UCA1 via the ACACCC motifs within UCA1 and destabilizes UCA1 through the recruitment of CCR4-NOT1 deadenylase complex.Meanwhile,binding of IMP1 prevents the association of miR-122-5p with UCA1,thereby shifting the availability of miR-122-5p from UCA1 to the target mRNAs and reducing the UCA1-mediated cell invasion.Accordingly, either IMP1 silencing or UCA1 overexpression resulted in reduced levels of free miR-122-5p within the cytoplasm, affecting miR-122-5p in regulating its target mRNAs.Our study provides initial evidence that interaction between IMP1 and UCA1 enhances UCA1 decay and competes for miR-122-5p binding,leading to the liberation of miR-122-5p activity and the reduction of cell invasiveness. |
