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.

10 GO annotations of cellular component

Name Definition
centrosome A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.
ciliary basal body A membrane-tethered, short cylindrical array of microtubules and associated proteins found at the base of a eukaryotic cilium (also called flagellum) that is similar in structure to a centriole and derives from it. The cilium basal body is the site of assembly and remodelling of the cilium and serves as a nucleation site for axoneme growth. As well as anchoring the cilium, it is thought to provide a selective gateway regulating the entry of ciliary proteins and vesicles by intraflagellar transport.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
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.
gamma-tubulin complex A multiprotein complex composed of gamma-tubulin and other non-tubulin proteins. Gamma-tubulin complexes are localized to microtubule organizing centers, and play an important role in the nucleation of microtubules. The number and complexity of non-tubulin proteins associated with these complexes varies between species.
microtubule cytoskeleton The part of the cytoskeleton (the internal framework of a cell) composed of microtubules and associated proteins.
microtubule organizing center An intracellular structure that can catalyze gamma-tubulin-dependent microtubule nucleation and that can anchor microtubules by interacting with their minus ends, plus ends or sides.
midbody A thin cytoplasmic bridge formed between daughter cells at the end of cytokinesis. The midbody forms where the contractile ring constricts, and may persist for some time before finally breaking to complete cytokinesis.
neuron projection A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

gamma-tubulin binding Binding to the microtubule constituent protein gamma-tubulin.
microtubule binding Binding to a microtubule, a filament composed of tubulin monomers.
protein serine kinase activity Catalysis of the reactions

13 GO annotations of biological process

Name Definition
cell cycle The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
cell division The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.
cilium organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a cilium, a specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.
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 bundle formation A process that results in a parallel arrangement of microtubules.
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.
nervous system development The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.
positive regulation of cell cycle Any process that activates or increases the rate or extent of progression through the cell cycle.
positive regulation of cilium assembly Any process that activates or increases the frequency, rate or extent of the formation of a cilium.
positive regulation of NLRP3 inflammasome complex assembly Any process that activates or increases the frequency, rate or extent of NLRP3 inflammasome complex assembly.
positive regulation of protein localization to centrosome Any process that activates or increases the frequency, rate or extent of protein localization to centrosome.
protein phosphorylation The process of introducing a phosphate group on to a protein.
regulation of centrosome cycle Any process that modulates the frequency, rate or extent of the centrosome cycle, the processes of centrosome duplication and separation.
