Insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3)

RNA-binding factor that may recruit target transcripts into 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 strikes 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.
