Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0001406
UniProt IDQ9Y6M1
Primary gene name(s)IGF2BP2
Synonym gene name(s)IMP2, VICKZ2
Protein nameInsulin-like growth factor 2 mRNA-binding protein 2
Protein functionRNA-binding factor that recruits 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, By similarity. Binds to the 5'-UTR of the insulin-like growth factor 2, IGF2 mRNAs. Binding is isoform-specific. Binds to beta-actin/ACTB and MYC transcripts. {ECO:0000250, ECO:0000269|PubMed:23640942, ECO:0000269|PubMed:9891060}.
Subcellular locationNucleus. Cytoplasm. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Localizes at the connecting piece and the tail of the spermatozoa. In response to cellular stress, such as oxidative stress, recruited to stress granules.
