|Other Names||Midkine, MK, Amphiregulin-associated protein, ARAP, Midgestation and kidney protein, Neurite outgrowth-promoting factor 2, Neurite outgrowth-promoting protein, MDK, MK1, NEGF2|
|Target/Specificity||A synthetic peptide corresponding to residues on the C-terminus of human Midkine was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Midkine Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Developmentally regulated, secreted growth factor homologous to pleiotrophin (PTN), which has heparin binding activity. Binds anaplastic lymphoma kinase (ALK) which induces ALK activation and subsequent phosphorylation of the insulin receptor substrate (IRS1), followed by the activation of mitogen-activated protein kinase (MAPK) and PI3-kinase, and the induction of cell proliferation. Involved in neointima formation after arterial injury, possibly by mediating leukocyte recruitment. Also involved in early fetal adrenal gland development (By similarity).|
|Tissue Location||Expressed in various tumor cell lines. In insulinoma tissue predominantly expressed in precancerous lesions|

Midkine (MK) is a 13 kDa heparin-binding polypeptide which enhances neurite outgrowth, neuronal cell survival and plasminogen activator activity. MK is structurally divided into two domains, and most of the biological activities are located on the C-terminal domain. Both domains consist of three antiparallel beta-strands, but the C-terminal domain has a long flexible hairpin loop where a heparin-binding consensus sequence is located (1). MK is a member of a highly conserved, developmentally regulated human gene family. The gene product exhibits neurite outgrowth-promoting activity and may play a role in nervous system development and/or maintenance. Expression of MK is predominant only for a short period from approximately one-half to two-thirds of the way through gestation; before and after that, it is barely detectable (2).
