NCBI Annotation Information: Note: IMP3 (Gene ID: 55272) and IGF2BP3 (Gene ID: 10643) share the IMP3 symbol/alias in common. IMP3 is a widely used alternative name for insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3), which can be confused with the official symbol for IMP3, U3 small nucleolar ribonucleoprotein (IMP3).
