IGF2BP1 a conserved trans-acting factor that can control translation of specific mRNAs in vivo. Contains four K homology (KH) domains and two RNA recognition motifs. It functions by binding to the 5' UTR of the target mRNAs and repressing translation. Target mRNAs include those encoding beta-actin and insulin-like growth factor 2 (IGF2). Tyrosine phosphorylation apparently abolishes translational repression of actin expression by decreasing its binding beta-actin mRNA. May have a role in progression of ovarian cancer. Contains nuclear export signals within the RNA-binding KH2 and KH4 domains. Aberrant expression may interfere with c-myc regulation. Note: This description may include information from UniProtKB.
