Also known as: igfbp2; igfbp2b
Summary: Enables insulin-like growth factor I binding activity and insulin-like growth factor II binding activity. Involved in negative regulation of DNA replication; negative regulation of developmental growth; and regulation of insulin-like growth factor receptor signaling pathway. Acts upstream of or within circulatory system development; negative regulation of cell population proliferation; and regulation of growth. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including gonad; head; immature eye; nervous system; and yolk syncytial layer. Human ortholog(s) of this gene implicated in obesity. Orthologous to human IGFBP2 (insulin like growth factor binding protein 2). [provided by Alliance of Genome Resources, Nov 2024]

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.
