DESCRIPTION

Also known as IF2B3_HUMAN, IGF2BP3, IMP3, KOC1, VICKZ3. RNA-binding factor that may recruit target transcripts to cytoplasmic protein-RNA complexes (mRNPs). This transcript 'caging' into mRNPs allows mRNA transport and transient storage. It also modulates the rate and location at which target transcripts encounter the translational apparatus and shields them from endonuclease attacks or microRNA-mediated degradation. Binds to the 3'-UTR of CD44 mRNA and stabilizes it, hence promotes cell adhesion and invadopodia formation in cancer cells. Binds to beta-actin/ACTB and MYC transcripts. Binds to the 5'-UTR of the insulin-like growth factor 2 (IGF2) mRNAs. Can form homooligomers and heterooligomers with IGF2BP1 and IGF2BP3 in an RNA-dependent manner. Interacts with IGF2BP1. Interacts with ELAVL1, DHX9 and HNRNPU.
