Summary

Midkine (MK, also called neurite growth promoting factor 2, NEGF-2), a product of a retinoic
acid responsive gene, is a secreted 13 kDa protein belonging to the family of heparin binding
growth/differentiation factors. MK shares 45% sequence identity with another member of this
family called Pleiotrophin (HB-GAM). Midkine is composed of two domains held together by
disulfide linkages. The C-terminally located domain contains two heparin binding sites and is
usually responsible for midkine activity. Part of the MK activity is enhanced by dimerization of
MK.

Midkine has been found in vertebrates from human to zebrafish and is most strongly expressed
in midgestation. In the adult MK expression is restricted. In addition to normal development,
MK is also involved in the pathogenesis of diseases, e.g. inflammatory diseases, human
carcinomas such as esophageal, stomach, colon, pancreatic, thyroid, lung, urinary,
hepatocellular, neuroblastoma, glioblastoma, Wilm´s tumor etc. High MK levels are associated
with poor prognosis in some types of cancer. The increased expression in many carcinomas
indicates that MK can be applied to the diagnosis of malignancy. Midkine is expressed during
the reparative stage of bone fractures, also supresses infection of cells by some viruses
including HIV. Anti-apoptotic and cell protecting activity of midkine makes it promising in
therapy.

Areas of investigation: Oncology, Inflammatory diseases, Preservation and repair of injured tissues.
