A protein kinase bound to the projection portion of MAP 2 (microtubule-associated protein 2)
In previous work we have demonstrated that the microtubule-associated protein 2 (MAP 2) molecule consists of two structural parts. One part of the molecule, referred to as the assembly-promoting domain, binds to the microtubule surface and is responsible for promoting microtubule assembly; the other represents a filamentous projection observed on the microtubule surface that may be involved in ...
متن کاملPhosphorylation of Xenopus mitogen-activated protein (MAP) kinase kinase by MAP kinase kinase kinase and MAP kinase.
Xenopus 45-kDa mitogen-activated protein (MAP) kinase kinase (MAPKK) is a serine/threonine/tyrosine kinase, which activates MAP kinase (MAPK) by phosphorylating its threonine and tyrosine residues. MAPKK is active only when its threonine and/or serine residues are phosphorylated. We have identified from Xenopus eggs two protein kinases responsible for phosphorylation of MAPKK. The two kinases a...
متن کاملA novel tobacco mitogen-activated protein (MAP) kinase kinase, NtMEK1, activates the cell cycle-regulated p43Ntf6 MAP kinase.
Two-hybrid screening of a tobacco BY-2 cell suspension cDNA library using the p43(Ntf6) mitogen-activated protein (MAP) kinase as bait resulted in the isolation of a cDNA encoding a protein with features characteristic of a MAP kinase kinase (MEK), which has been called NtMEK1. Two-hybrid interaction analysis and pull-down experiments showed a physical interaction between NtMEK1 and the tobacco...
متن کاملHuman endotoxemia activates p38 MAP kinase and p42/44 MAP kinase, but not c-Jun N-terminal kinase.
BACKGROUND All three major members of the MAPK family (i.e., p38 MAPK, p42/p44 MAPK, and c-Jun N terminal kinase (JNK)) have been shown to control cellular responses to inflammation in vitro. Therefore these kinases have been designated suitable targets for anti-inflammatory therapy. However, the extent to which these kinases are actually activated during inflammation in humans in vivo has not ...
متن کاملMolecular structure of a protein-tyrosine/threonine kinase activating p42 mitogen-activated protein (MAP) kinase: MAP kinase kinase.
MAP kinases p42mapk and p44mapk participate in a protein kinase cascade(s) important for signaling in many cell types and contexts. Both MAP kinases are activated in vitro by MAP kinase kinase, a protein-tyrosine and threonine kinase. A MAP kinase kinase cDNA was isolated from a rat kidney library by using peptide sequence data we obtained from MAP kinase kinase isolated from rabbit skeletal mu...
