Effector that is released into the host cell and affects host immune responses; it negatively modulates inflammation, macrophage autophagy, and cell death through redox-dependent signaling (PubMed:17259625, PubMed:21187903). Acts as an acetyltransferase. Acetylates 'Lys-55' of dual-specificity protein phosphatase 16 (DUSP16)/mitogen-activated protein kinase phosphatase-7 (MKP-7), a JNK-specific phosphatase; this leads to the inhibition of JNK-dependent autophagy, phagosome maturation, and ROS (reactive oxygen species) generation for enhanced intracellular survival of M.tuberculosis (PubMed:22547814). Inhibits Con A-mediated T-cell proliferation in vitro (PubMed:17449476). Treatment of T-cells with Eis inhibits ERK1/2, JAK pathway, and subsequent production of tumor necrosis factor-alpha (TNF-alpha) and interleukin-4 (IL-4); on the contrary, there is increased production of interferon-gamma (IFN-gamma) and interleukin-10 (IL-10), which indicates that immunity in response to Eis treatment is skewed away from a protective T(H)1 response and Eis disturbs the cross regulation of T-cells (PubMed:17449476). When expressed in M.smegmatis, enhances intracellular survival of the bacteria in host macrophages during infection (PubMed:10629183). UniProt

Subunit Structure
Homohexamer; trimer of dimers. UniProt
The Eis monomer consists of three regions that are assembled into a heart-shaped molecule (PubMed:21628583). This shape is formed by an unusual fusion of two general control non-derepressible 5 (GCN5)-related N-acetyltransferase (GNAT) regions and a C-terminal region (PubMed:21628583). The N-acetyltransferase domain of Eis is responsible for its modulation of ROS generation and proinflammatory responses in macrophages (PubMed:21187903). UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
