Summary: Enables insulin-like growth factor I binding activity and insulin-like growth factor II binding activity. Involved in several processes, including response to estradiol; response to estrogen; and response to retinoic acid. Located in apical plasma membrane; cytoplasmic vesicle; and extracellular space. Biomarker of hypertension and hypothyroidism. Human ortholog(s) of this gene implicated in obesity. Orthologous to human IGFBP2 (insulin like growth factor binding protein 2).

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.
