Insulin-Like Growth Factor 2 mRNA-Binding Protein 2 (IGFBP2) belongs to the RRM IMP VICKZ family. IGFBP2 is a cytoplasmic protein and contains four KH domains and two RRM (RNA recognition motif) domains. IGF2BP2 binds to the 5'-UTR of the Insulin-Like Growth Factor 2 (IGF2) mRNA. This binding is isoform-specific. IGF2BP2 may regulate translation of target mRNAs. Genetic variation at the IGF2BP2 gene has been associated with type 2 diabetes (T2D) by genome-wide association studies and by replication analyses.
Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) is a member of the IGF-II mRNA-binding protein (IMP) family. IGF2BP2 is a member of a family of mRNA binding proteins that, collectively, have been shown to bind to several different mRNAs in mammalian cells, including one of the mRNAs encoding insulin-like growth factor-2. Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) is involved in the stimulation of insulin action. IGF2BP2 IMP2 is expressed in oocytes, granulosa cells of small and growing follicles, Leydig cells, spermatogonia, and semen (at protein level). It is also expressed in testicular cancer (at protein level). It is expressed weakly in the heart, placenta, skeletal muscle, bone marrow, colon, kidney, salivary glands, testis, and pancreas. IGF2BP2 binds to the 5'-UTR of the insulin-like growth factor 2 (IGF2) mRNAs. This binding is isoform-specific. IGF2BP2 may regulate the translation of target mRNAs.
