|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||MARK3 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Serine/threonine-protein kinase (PubMed:23666762). Involved in the specific phosphorylation of microtubule-associated proteins for MAP2 and MAP4. Phosphorylates the microtubule- associated protein MAPT/TAU (PubMed:23666762). Phosphorylates CDC25C on 'Ser-216'. Regulates localization and activity of some histone deacetylases by mediating phosphorylation of HDAC7, promoting subsequent interaction between HDAC7 and 14-3-3 and export from the nucleus (PubMed:16980613). Negatively regulates the Hippo signaling pathway and antagonizes the phosphorylation of LATS1. Cooperates with DLG5 to inhibit the kinase activity of STK3/MST2 toward LATS1 (PubMed:28087714).|
|Cellular Location||Cell membrane; Peripheral membrane protein. Cell projection, dendrite. Cytoplasm|

MARK3 is a dual-specificity protein kinase that controls entry into mitosis by dephosphorylating Cdc2 on both threonine 14 and tyrosine 15. MARK3 is phosphorylated on serine 216 throughout interphase but not during mitosis. Serine 216 phosphorylation mediates the binding of 14-3-3 protein to MARK3, and MARK3/14-3-3 complexes are present throughout interphase but not during mitosis (1). Kinase suppressor of Ras (KSR) is a conserved component of the Ras pathway that interacts directly with MEK and MAPK. It has been shown that KSR1 translocates from the cytoplasm to the cell surface in response to growth factor treatment and that this process is regulated by MARK3 (2). MARK3 seems to be a positive regulator of the beta-catenin pathway and an inhibitor of the JNK pathway. These findings show that MARK3, a regulator of polarity, is also a modulator of Wnt-beta-catenin signaling, indicating a link between two important developmental pathways (3).
