Midkine, also known as neurite growth-promoting factor 2, is a heparin-binding nonglycosylated low molecular weight protein. It is expressed in a variety of cell types during embryogenesis, and has functions related to cell growth, migration and angiogenesis. Midkine signals through the anaplastic lymphoma kinase (ALK) receptor which stimulates phosphorylation and kinase activation events and results in cell proliferation.
