  Domain Name: GST_C_AIMP2
Glutathione S-transferase C-terminal-like, alpha helical domain of Aminoacyl tRNA synthetase complex-Interacting Multifunctional Protein 2. Glutathione S-transferase (GST) C-terminal domain family, Aminoacyl tRNA synthetase complex-Interacting Multifunctional Protein (AIMP) 2 subfamily; AIMPs are non-enzymatic cofactors that play critical roles in the assembly and formation of a macromolecular multi-tRNA synthetase protein complex that functions as a molecular hub to coordinate protein synthesis. There are three AIMPs, named AIMP1-3, which play diverse regulatory roles. AIMP2, also called p38 or JTV-1, contains a C-terminal domain with similarity to the C-terminal alpha helical domain of GSTs. It plays an important role in the control of cell fate via antiproliferative (by enhancing the TGF-beta signal) and proapoptotic (activation of p53 and TNF-alpha) activities. Its roles in the control of cell proliferation and death suggest that it is a potent tumor suppressor. AIMP2 heterozygous mice with lower than normal expression of AIMP2 show high susceptibility to tumorigenesis. AIMP2 is also a substrate of Parkin, an E3 ubiquitin ligase that is involved in the ubiquitylation and proteasomal degradation of its substrates. Mutations in the Parkin gene is found in 50% of patients with autosomal-recessive early-onset parkinsonism. The accumulation of AIMP2, due to impaired Parkin function, may play a role in the pathogenesis of Parkinson's disease.

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
