ID:IF2B2_HUMAN DESCRIPTION: RecName: Full=Insulin-like growth factor 2 mRNA-binding protein 2; Short=IGF2 mRNA-binding protein 2; Short=IMP-2; AltName: Full=Hepatocellular carcinoma autoantigen p62; AltName: Full=IGF-II mRNA-binding protein 2; AltName: Full=VICKZ family member 2; FUNCTION: Binds to the 5'-UTR of the insulin-like growth factor 2 (IGF2) mRNAs. Binding is isoform-specific. May regulate translation of target mRNAs. SUBUNIT: Interacts with HNRPD and IGF2BP1. INTERACTION: Q14103-4:HNRNPD; NbExp=4; IntAct=EBI-1024419, EBI-432545; SUBCELLULAR LOCATION: Cytoplasm. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Localizes at the connecting piece and the tail of the spermatozoa. TISSUE SPECIFICITY: Expressed in oocytes, granulosa cells of small and growing follicles, Leydig cells, spermatogonia and semen (at protein level). Expressed in testicular cancer (at protein level). Expressed weakly in heart, placenta, skeletal muscle, bone marrow, colon, kidney, salivary glands, testis and pancreas. Detected in fetal liver, fetal ovary, gonocytes and interstitial cells of the testis. DOMAIN: The third and fourth KH domains are important for binding to the untranslated region (UTR) of target mRNA. MISCELLANEOUS: Autoantibodies against IGF2BP2 are detected in sera from some patients with hepatocellular carcinoma. SIMILARITY: Belongs to the RRM IMP/VICKZ family. SIMILARITY: Contains 4 KH domains. SIMILARITY: Contains 2 RRM (RNA recognition motif) domains. SEQUENCE CAUTION: Sequence=AAH21290.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
