Descriptions

MAPKAPK2 is a stress-activated serine/threonine-protein kinase. MAPKAPK2, contains an autoinhibitory α-helix overlapping with a leucine-rich nuclear export signal (NES), and also lies close to the nuclear localization signal (NLS). The closed conformation of MAPKAPK2 prevents exportin binding to NES. Phosphorylation of MAPKAPK2 at threonine 317 induces a conformational change, thus unmasks and increases the activity of NES.

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.
nucleoplasm That part of the nuclear content other than the chromosomes or the nucleolus.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

7 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
calcium-dependent protein serine/threonine kinase activity Calcium-dependent catalysis of the reactions
calmodulin binding Binding to calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
calmodulin-dependent protein kinase activity Calmodulin-dependent catalysis of the reactions
mitogen-activated protein kinase binding Binding to a mitogen-activated protein kinase.
protein serine kinase activity Catalysis of the reactions
protein serine/threonine kinase activity Catalysis of the reactions

6 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.
macropinocytosis An endocytosis process that results in the uptake of liquid material by cells from their external environment by the 'ruffling' of the cell membrane to form heterogeneously sized intracellular vesicles called macropinosomes, which can be up to 5 micrometers in size.
phosphorylation The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
response to cytokine Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cytokine stimulus.
response to lipopolysaccharide Any process that results in a change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipopolysaccharide stimulus; lipopolysaccharide is a major component of the cell wall of gram-negative bacteria.
toll-like receptor signaling pathway The series of molecular signals initiated by a ligand binding to a toll-like receptor of a target cell. Toll-like receptors directly bind pattern motifs from a variety of microbial sources to initiate an innate immune response.
