Descriptions

(Annotation based on sequence homology with Q02750)
MAP2K1 encodes for Dual specificity mitogen-activated protein kinase kinase 1, belongs to MAP2Ks family, plays an important role in MAP kinase signal transduction pathway. The α-helix 1 in the activation loop of MAP2K1 is shifted outwards from the active site because of the NRD. NRD of MAP2K1 prevents MAP2K1 changing to the active conformation. The autoinhibitory state of MAP2K1 is more stable as dimer in the absence of its own substrates or other interacting partners. The several interactions span from the N-terminal to the C-terminal to form dimer. Dimerization of MAP2K1 block access of the substrate binding site and the activation loop from macromolecules.

Functions

Description
EC Number 2.7.12.2 Dual-specificity kinases (those acting on Ser/Thr and Tyr residues)
Subcellular Localization
  • Cytoplasm, cytoskeleton, microtubule organizing center, centrosome
  • Cytoplasm, cytoskeleton, microtubule organizing center, spindle pole body
  • Cytoplasm
  • Nucleus
  • Membrane ; Peripheral membrane protein
  • Localizes at centrosomes during prometaphase, midzone during anaphase and midbody during telophase/cytokinesis
  • Membrane localization is probably regulated by its interaction with KSR1

4 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
membrane A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
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.
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.

5 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
MAP kinase kinase activity Catalysis of the concomitant phosphorylation of threonine (T) and tyrosine (Y) residues in a Thr-Glu-Tyr (TEY) thiolester sequence in a MAP kinase (MAPK) substrate.
protein serine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate.
protein serine/threonine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.
protein tyrosine kinase activity Catalysis of the reaction: ATP + a protein tyrosine = ADP + protein tyrosine phosphate.

2 GO annotations of biological process

Name Definition
MAPK cascade An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain an additional tiers: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.
neuron differentiation The process in which a relatively unspecialized cell acquires specialized features of a neuron.
