Summary
The protein encoded by this gene is primarily found in the nucleolus, where it can bind to the 5' UTR of the insulin-like growth factor II leader 3 mRNA and may repress translation of insulin-like growth factor II during late development. The encoded protein contains several KH domains, which are important in RNA binding and are known to be involved in RNA synthesis and metabolism. A pseudogene exists on chromosome 7, and there are putative pseudogenes on other chromosomes. [provided by RefSeq, Jul 2008]
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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
