The insulin-like growth factor-2 mRNA-binding proteins 1, 2, and 3 (IGF2BP1, IGF2BP2, IGF2BP3) belong to a conserved family of RNA-binding, oncofetal proteins. Several studies have shown that these proteins act in various important aspects of cell function, such as cell polarization, migration, morphology, metabolism, proliferation and differentiation.

The analysis of protein-RNA association in vitro commonly involves radiolabeled in vitro transcribed RNAs. Nucleotides labeled with near-infrared (NIR) dyes provide promising alternatives for studying protein-RNA binding in vitro. However, it remained elusive whether random labeling of RNA probes by NIR dyes interferes with protein binding. Here, we(More)
The IGF2 mRNA-binding protein family (IGF2BPs) directs the cytoplasmic fate of various target mRNAs and controls essential cellular functions. The three IGF2BP paralogues expressed in mammals comprise two RNA-recognition motifs (RRM) as well as four KH domains. How these domains direct IGF2BP paralogue-dependent protein function remains largely elusive. In(More)
SCOPE Osteoblasts produce fibroblast growth factor 23 (FGF23), a hormone inhibiting renal phosphate reabsorption and the formation of biologically active vitamin D, calcitriol. FGF23-deficient mice age rapidly and develop age-associated diseases at least in part due to massive calcification. Elevated FGF23 serum levels are detected in patients suffering(More)
