Descriptions

IpaH9.8 E3 ligase inhibits MAPK kinase dependent signaling by targeting components of this pathway and disrupts both NF-κB-dependent gene expression and the activity of U2AF35 via the ubiquitination. In a study with ipaH9.8, the N-terminal domain (leucine-rich repeat) may be inhibitory for the autoinhibition activity of the full-length IpaH9.8 and substrate binding releases this inhibition.

Functions

Description
EC Number 2.3.2.27 Aminoacyltransferases
Subcellular Localization
  • Secreted
  • Host cytoplasm
  • Host nucleus
  • Secreted via Mxi-Spa type III secretion system (T3SS), and delivered into the host cytoplasm
  • Transported into the host nucleus
  • This transport is independent of cytosolic factors, but dependent on temperature and partly on ATP/GTP

3 GO annotations of cellular component

Name Definition
extracellular region The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
host cell cytosol The part of the host cell cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
host cell nucleus A membrane-bounded organelle as it is found in the host cell in which chromosomes are housed and replicated. The host is defined as the larger of the organisms involved in a symbiotic interaction.

1 GO annotations of molecular function

Name Definition
ubiquitin-protein transferase activity Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.

1 GO annotations of biological process

Name Definition
protein K27-linked ubiquitination A protein ubiquitination process in which a polymer of ubiquitin, formed by linkages between lysine residues at position 27 of the ubiquitin monomers, is added to a protein.
