Summary: Enables D-mannose binding activity and insulin-like growth factor binding activity. Predicted to be involved in several processes, including liver development; positive regulation by host of viral process; and response to retinoic acid. Located in membrane and nuclear envelope lumen. Is expressed in several structures, including alimentary system; cardiovascular system; central nervous system; early conceptus; and genitourinary system. Human ortholog(s) of this gene implicated in diabetes mellitus (multiple); hepatocellular carcinoma; in situ carcinoma (multiple); and nephroblastoma. Orthologous to human IGF2R (insulin like growth factor 2 receptor). [provided by Alliance of Genome Resources, Jun 2025]

Igf2bp2 is a binding partner of Airn in cardiomyocytes. Airn binds to Igf2bp2 to control the translation of several genes. Silencing of Airn caused less binding of Igf2bp2 to other mRNAs and reduced translation of Igf2bp2 protein.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
