Enables protein serine/threonine kinase activator activity; signaling receptor binding activity; and steroid binding activity. Involved in several processes, including cellular response to hormone stimulus; negative regulation of cell death; and positive regulation of cell differentiation. Located in several cellular components, including interstitial matrix; neuronal cell body; and platelet alpha granule. Used to study brain ischemia; diabetic neuropathy; and hypertension. Biomarker of several diseases, including alcoholic neuropathy; artery disease (multiple); congenital diaphragmatic hernia; folic acid deficiency anemia; and hypothyroidism (multiple). Human ortholog(s) of this gene implicated in several diseases, including acne; brain ischemia; diabetes mellitus (multiple); myopia; and neurodegenerative disease (multiple). Orthologous to human IGF1 (insulin like growth factor 1). [provided by Alliance of Genome Resources, Apr 2022]
