The C-domain plays a role in neuronal development, whereas the N-domain is important for protein stability and dimerization. MK is involved in development, reproduction, repair, inflammation, innate immunity, control of blood pressure and angiogenesis.\u003cbr\u003e\nMK is strongly expressed during embryogenesis and due to its distribution in the embryo it has been proposed to play a role in neurogenesis, epithelial-mesenchymal interactions and mesoderm remodeling. Expression in adult tissues is restricted to the kidney, epidermis, bronchial epithelium, lymphocytes and macrophages, but it is strongly expressed in the brain, kidney, blood vessels and heart after tissue injury as well as during inflammation, infection and oncogenesis. During inflammation, substratum-bound MK enhances neutrophil and macrophage migration directly and through induction of chemokine expression. On the other hand, soluble MK is associated with differentiation of regulatory T-cells, induction of epithelial-mesenchymal transition, angiogenesis, fibrinolytic and anti-microbial activity.\u003cbr\u003e\nMK signaling is mediated by cell surface receptors as well as membrane proteins such as Protein Tyrosine Phosphatase ζ (PTPζ), low density lipoprotein receptor-related proteins (LRP), Notch2, integrins, anaplastic lymphoma kinase (ALK) and neuroglycan C. Binding of MK to PTPζ induces tyrosine phosphorylation in β-catenin and Wnt signaling inhibition. Furthermore it induces phosphorylation of PI3K, MAPK, PKC and Src family kinase. Binding of MK to LRP leads to embryonic neuronal survival and prevention of hypoxic injury via Akt and HIF1α. Binding of MK to integrins activates focal adhesion kinase, paxillin and STAT1α pathway leading to increase invasiveness of cancer cells. Activation of ALK by MK leads to phosphorylation of IRS-1, MAPK, PI3K and activation of NF-κB.\u003cbr\u003e\nDue to its multifunctionality, MK has become an emerging target of drug development for the treatment of multiple diseases. On the one hand, administration of MK ameliorates ischemic injury, enhances oocyte maturation and promotes neurogenesis therefore limiting the progression of neurodegenerative diseases. However on the other hand, due to its over-expression in malignant tumors and in inflammation, MK inhibitors may be useful in the treatment of cancer, multiple sclerosis, hypertension and osteoporosis.\u003cbr\u003e\nREACH authorisation\u003cbr\u003e\nAbcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.\u003cbr\u003e\nIt is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843551121577,"sku":"ab193761","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab193761","provider":"Iright","version":"1.0","type":"link"}
