Serine/threonine-protein kinase involved in cell polarity and microtubule dynamics regulation. Phosphorylates DCX, MAP2, MAP4 and MAPT/TAU. Involved in cell polarity by phosphorylating the microtubule-associated proteins MAP2, MAP4 and MAPT/TAU at KXGS motifs, causing detachment from microtubules, and their disassembly. Involved in the regulation of neuronal migration through its dual activities in regulating cellular polarity and microtubule dynamics, possibly by phosphorylating and regulating DCX. Also acts as a positive regulator of the Wnt signaling pathway, probably by mediating phosphorylation of dishevelled proteins (DVL1, DVL2 and/or DVL3).

Microtubule-associated protein/microtubule affinity regulating kinases (MARKs), also called partition-defective (Par-1) kinases, are serine/threonine protein kinases (STKs) that catalyze the transfer of the gamma-phosphoryl group from ATP to S/T residues on protein substrates. They phosphorylate the tau protein and related microtubule-associated proteins (MAPs) on tubulin binding sites to induce detachment from microtubules, and are involved in the regulation of cell shape and polarity, cell cycle control, transport, and the cytoskeleton. Mammals contain four proteins, MARK1-4, encoded by distinct genes belonging to this subfamily, with additional isoforms arising from alternative splicing. MARK1/2, through their activation by death-associated protein kinase (DAPK), modulates polarized neurite outgrowth. MARK1, also called Par-1c, is also involved in axon-dendrite specification, and SNPs on the MARK1 gene is associated with autism spectrum disorders. MARK2, also called Par-1b, is implicated in many physiological processes including fertility, immune system homeostasis, learning and memory, growth, and metabolism. MARK3, also called Par-1a, is implicated in gluconeogenesis and adiposity; mice deficient with MARK3 display reduced adiposity, resistance to hepatic steatosis, and defective gluconeogensis. MARKs contain an N-terminal catalytic kinase domain, a ubiquitin-associated domain (UBA), and a C-terminal kinase associated domain (KA1). The KA1 domain binds anionic phospholipids and may be involved in membrane localization as well as in auto-inhibition of the kinase domain. Length = 98

Protein kinases catalyse the transfer of the gamma phosphate from nucleotide triphosphates (often ATP) to one or more amino acid residues in a protein substrate side chain, resulting in a conformational change affecting protein function. Phosphoprotein phosphatases catalyse the reverse process. Protein kinases fall into three broad classes, characterised with respect to substrate specificity []: Serine/threonine-protein kinases Tyrosine-protein kinases Dual specific protein kinases (e.g. MEK - phosphorylates both Thr and Tyr on target proteins) Protein kinase function has been evolutionarily conserved from Escherichia coli to human []. Protein kinases play a role in a multitude of cellular processes, including division, proliferation, apoptosis, and differentiation []. Phosphorylation usually results in a functional change of the target protein by changing enzyme activity, cellular location, or association with other proteins. The catalytic subunits of protein kinases are highly conserved, and several structures have been solved [], leading to large screens to develop kinase-specific inhibitors for the treatments of a number of diseases []. Eukaryotic protein kinases [, , , , ] are enzymes that belong to a very extensive family of proteins which share a conserved catalytic core common with both serine/threonine and tyrosine protein kinases. There are a number of conserved regions in the catalytic domain of protein kinases. In the N-terminal extremity of the catalytic domain there is a glycine-rich stretch of residues in the vicinity of a lysine residue, which has been shown to be involved in ATP binding. In the central part of the catalytic domain there is a conserved aspartic acid residue which is important for the catalytic activity of the enzyme []. Members of the KIN2/PAR-1/MARK kinase subfamily are conserved from yeast to human and share the same domain organisation: an N-terminal kinase domain (IPR000719 from INTERPRO) and a C-terminal kinase associated domain 1 (KA1). Some members of the KIN1/PAR-1/MARK family also contain an UBA domain (IPR000449 from INTERPRO). Members of this kinase subfamily are involved in various biological processes such as cell polarity, cell cycle control, intracellular signalling, microtubule stability and protein stability []. The function of the KA1 domain is not yet known. Some proteins known to contain a KA1 domain are listed below: Mammalian MAP/microtubule affinity-regulating kinases (MARK 1,2,3). They regulate polarity in neuronal cell models and appear to function redundantly in phosphorylating MT-associated proteins and in regulating MT stability []. Mammalian maternal embryonic leucine zipper kinase (MELK). It phosphorylates ZNF622 and may contribute to its redirection to the nucleus. It may be involved in the inhibition of spliceosome assembly during mitosis. Caenorhabditis elegans and drosophila PAR-1 protein. It is required for establishing polarity in embryos where it is asymmetrically distributed []. Fungal Kin1 and Kin2 protein kinases involved in regulation of exocytosis. They localise to the cytoplasmic face of the plasma membrane []. Plant KIN10 and KIN11 proteins, catalytic subunits of the putative trimeric SNF1-related protein kinase (SnRK) complex. This entry represents the KA1 domain.; GO: 0004674 protein serine/threonine kinase activity, 0005524 ATP binding, 0006468 protein phosphorylation; PDB: 3OSE_A 1V5S_A 1UL7_A.
