Descriptions

Nek9 is a NIMA-related kinase essential for proper mitotic spindle assembly. A human homolog Nek7 (Q8TDX7) is subject to autoinhibition by a tyrosine motif, Tyr97, like human Nek6 (Tyr108). This is because the Y97A mutation is more active than wild-type Nek7. A similar tyrosine motif is also found in mouse Nek9.

3 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
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.

4 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
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

8 GO annotations of biological process

Name Definition
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 hippo signaling Any process that stops, prevents, or reduces the frequency, rate or extent of hippo signaling.
negative regulation of protein localization to nucleus Any process that stops, prevents or reduces the frequency, rate or extent of protein localization to nucleus.
peptidyl-serine autophosphorylation The phosphorylation by a protein of one or more of its own serine amino acid residues, or a serine residue on an identical protein.
peptidyl-serine phosphorylation The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine.
positive regulation of protein binding Any process that activates or increases the frequency, rate or extent of protein binding.
protein phosphorylation The process of introducing a phosphate group on to a protein.
