Descriptions

MAPK1 encodes Mitogen-activated protein kinase 1, and is involved in diverse cellular responses by phosphorylating cytoplasmic and nuclear proteins. Unlike other MAP kinases, MAPK1 activates via dual phosphorylation of Thr-186 and Tyr-193 within the activation lip, and mutations at Q105 alone were sufficient for autoactivation. Additionally, in the inactive form, L76, Q10 and I87 form a structural unit that restrains intramolecular autophosphorylation by preventing interactions between activation lip residues and the catalytic base (D149) needed for phosphoryl transfer. Mutations at L76, I87 and additionally S153 increased basal specific activity via autophosphorylation of Thr-186 and Tyr-193.

6 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytoplasmic stress granule A dense aggregation in the cytosol composed of proteins and RNAs that appear when the cell is under stress.
mating projection tip The apex of the mating projection in unicellular fungi exposed to mating pheromone; site of polarized growth.
mitochondrion A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
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.
periplasmic space The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).

6 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
identical protein binding Binding to an identical protein or proteins.
MAP kinase activity Catalysis of the reaction
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

10 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.
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.
invasive growth in response to glucose limitation A growth pattern exhibited by budding haploid cells under certain growth conditions, in which cells retain the typical axial budding pattern of haploids, but become elongated and fail to separate after division; during growth on a solid substrate, this results in penetration of cells into the agar medium. An example of this process is found in Saccharomyces cerevisiae.
negative regulation of MAPK cascade Any process that stops, prevents, or reduces the frequency, rate or extent of signal transduction mediated by the MAPKKK cascade.
pheromone response MAPK cascade A MAPK cascade that is part of a pheromone response ending in conjugation with cellular fusion.
pheromone-dependent signal transduction involved in conjugation with cellular fusion A signal transduction process resulting in the relay, amplification or dampening of a signal generated in response to pheromone exposure in organisms that undergo conjugation with cellular fusion. An example of this process is found in Saccharomyces cerevisiae.
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.
positive regulation of protein export from nucleus Any process that activates or increases the frequency, rate or extent of directed movement of proteins from the nucleus into the cytoplasm.
retrotransposon silencing Any process that decreases the frequency, rate or extent of retrotransposition. Retrotransposons are a subset of transposable elements that use an RNA intermediate and reverse transcribe themselves into the genome.
