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.
