Descriptions

MARK1 is a Ser/Thr protein kinase involved in various cellular processes. It is part of the CAMK-like kinase family and has roles in diseases like Alzheimer’s and cancer. The kinase’s autoinhibition is mediated by its C-terminal KA1 domain, which interacts with the kinase domain to prevent substrate binding and activation. The KA1 domain binds to the αD-helix, blocking the peptide substrate binding site and inhibiting the kinase. This autoinhibition is alleviated by the binding of anionic phospholipid membranes to the KA1 domain, which reverses MARK1 autoinhibition and stimulates kinase activity.

4 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytoskeleton A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
dendrite A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

9 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
magnesium ion binding Binding to a magnesium (Mg) ion.
phosphatidic acid binding Binding to phosphatidic acid, any of a class of glycerol phosphate in which both the remaining hydroxyl groups of the glycerol moiety are esterified with fatty acids.
phosphatidylinositol-4,5-bisphosphate binding Binding to phosphatidylinositol-4,5-bisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 4' and 5' positions.
phosphatidylserine binding Binding to phosphatidylserine, a class of glycophospholipids in which a phosphatidyl group is esterified to the hydroxyl group of L-serine.
protein kinase activity Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction
protein serine kinase activity Catalysis of the reactions
protein serine/threonine kinase activity Catalysis of the reactions
tau-protein kinase activity Catalysis of the reaction

12 GO annotations of biological process

Name Definition
cytoskeleton organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures.
establishment of mitochondrion localization The directed movement of the mitochondrion to a specific location.
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
microtubule cytoskeleton organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures comprising microtubules and their associated proteins.
negative regulation of epithelial to mesenchymal transition Any process that decreases the rate, frequency, or extent of epithelial to mesenchymal transition. Epithelial to mesenchymal transition where an epithelial cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell.
negative regulation of gene expression Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).
neuron migration The characteristic movement of an immature neuron from germinal zones to specific positions where they will reside as they mature.
positive regulation of gene expression Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).
protein phosphorylation The process of introducing a phosphate group on to a protein.
regulation of dendrite development Any process that modulates the frequency, rate or extent of dendrite development.
regulation of neuron projection development Any process that modulates the rate, frequency or extent of neuron projection development. Neuron projection development is the process whose specific outcome is the progression of a neuron projection over time, from its formation to the mature structure. A neuron projection is any process extending from a neural cell, such as axons or dendrites (collectively called neurites).
Wnt signaling pathway The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell and ending with a change in cell state.
