The protein encoded by this gene is part of the aminoacyl-tRNA synthetase complex, which contains nine different aminoacyl-tRNA synthetases and three non-enzymatic factors. The encoded protein is one of the non-enzymatic factors and is required for assembly and stability of the complex. [provided by RefSeq, May 2016] See more...

Diseases associated with AIMP2 include Leukodystrophy, Hypomyelinating, 17 and Leukodystrophy, Hypomyelinating, 3. Among its related pathways are tRNA Aminoacylation and Viral mRNA Translation.

UniProtKB/Swiss-Prot Summary for AIMP2 Gene

  • Required for assembly and stability of the aminoacyl-tRNA synthase complex (PubMed:19131329). Mediates ubiquitination and degradation of FUBP1, a transcriptional activator of MYC, leading to MYC down-regulation which is required for aveolar type II cell differentiation. Blocks MDM2-mediated ubiquitination and degradation of p53/TP53. Functions as a proapoptotic factor.

    320 amino acids
    Molecular mass:
    35349 Da
    Quaternary structure:
    • Part of the multisynthetase complex (MSC), a multisubunit complex that groups tRNA ligases for Arg (RARS1), Asp (DARS1), Gln (QARS1), Ile (IARS1), Leu (LARS1), Lys (KARS1), Met (MARS1) the bifunctional ligase for Glu and Pro (EPRS1) and the auxiliary subunits AIMP1/p43, AIMP2/p38 and EEF1E1/p18 (PubMed:24312579, PubMed:19131329, PubMed:19289464). Interacts (via N-terminus) with KARS1 (PubMed:9878398, PubMed:15220430, PubMed:18029264, PubMed:23159739, PubMed:26074468). Interacts with EPRS1 (PubMed:26472928). Forms a linear complex that contains MARS1, EEF1E1, EPRS1 and AIMP2 that is at the core of the multisubunit complex (PubMed:26472928). Binds FUBP1 (via C-terminus). Interacts in both its unphosphorylated and phosphorylated forms with p53/TP53 (via N-terminus) in the nucleus following UV irradiation. Interacts (via N-terminus) with PRKN/parkin (via first RING-type domain) (PubMed:16135753). Interacts with TARS3 (PubMed:24312579).

Post-translational modifications for AIMP2 Gene

  • Phosphorylated on serine residues in response to UV irradiation.
  • Ubiquitinated by PRKN, leading to its degradation by the proteasome. Mutant PRKN fails to ubiquitinate AIMP2 efficiently, allowing its accumulation which may contribute to neurodegeneration associated with Parkinson disease.
