DescriptionArtemin is a Neurotrophin member of the Glial cell line-derived Neurotrophic Factor (GDNF) ligand family. Artemin is highly expressed in the adult pituitary gland, placenta, and trachea, and shows low level expression in the brain, spinal cord, and peripheral tissues. Artemin signals through the RET receptor and GDNF family receptor α 3 (GFR α 3) co-receptor complex to support neuronal survival.
Activity AssayHuman Artemin is fully biologically active when compared to standards. The ED50, calculated by the dose-dependant proliferation assay the SH-SY5Y cell line, was found to be 4 - 8 ng/ml. The activity can also be determined by its ability to promote survival and neurite outgrowth.
