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.

1 GO annotations of cellular component

Name Definition
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

5 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.
MAP kinase kinase kinase activity Catalysis of the phosphorylation and activation of a MAP kinase kinase; each MAP kinase kinase can be phosphorylated by any of several MAP kinase kinase kinases.
protein serine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate.
protein serine/threonine/tyrosine kinase activity Catalysis of the reactions: ATP + a protein serine = ADP + protein serine phosphate; ATP + a protein threonine = ADP + protein threonine phosphate; and ATP + a protein tyrosine = ADP + protein tyrosine phosphate.

2 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.
immune system process Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats.
