Summary: Enables insulin-like growth factor receptor binding activity. Acts upstream of or within dorsal/ventral pattern formation; positive regulation of cell population proliferation; and regulation of lipid metabolic process. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including blood plasma; digestive system; eye; female organism; and musculature system. Human ortholog(s) of this gene implicated in several diseases, including acne; artery disease (multiple); diabetes mellitus (multiple); myopia; and neurodegenerative disease (multiple). Orthologous to human IGF1 (insulin like growth factor 1). [provided by Alliance of Genome Resources, Dec 2024]

Data show that a group of epithelial cells expressing insulin-like growth factor binding protein 5a (igfbp5a) take up Ca(2+) and proliferate under low Ca(2+) conditions because of activation of insulin like growth factors (IGF) signaling.

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.
