library_construction_protocol: The IGF2BP2-bound RNA was isolated from the immunoprecipitation of anti-IGF2BP2 using Trizol (Invitrogen). Complementary DNA (cDNA) libraries were prepared with the KAPA RNA Hyper Prep Kit (KAPA, KK8541) according to the manufacturer's procedure and high-throughput sequencing of the cDNA libraries was performed on an Illumina Xtenplatform for 150 bp paired-end sequencing.
