Enables growth factor activity. Involved in several processes, including animal organ regeneration; positive regulation of angiogenesis; and positive regulation of myelination. Located in extracellular space. Used to study brain infarction. Biomarker of cholangiocarcinoma. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); autosomal recessive nonsyndromic deafness 39; eye disease (multiple); neuropathy (multiple); and scleroderma (multiple).
