LmnA binds AIMP3 via its extreme C-terminus. Together these findings provide a structural insight for understanding the interaction between AIMP3 and LmnA in AIMP3 degradation.
analysis of the heterotetrameric complex structure of the glutathione transferase (GST) domains shared among the four MSC components, methionyl-tRNA synthetase (MRS), glutaminyl-prolyl-tRNA synthetase (EPRS), AIMP2 and AIMP3
AIMP3 was shown to be involved in the cellular aging of human mesenchymal stem cells.
Identification of EEf1E1 and OBFC2B as novel BRCA1-partner genes in the DNA double-strand break repair pathway.
AIMP3 stabilizes and protects methionyl-tRNA synthetase and eIF2gamma through the binding interactions.
AIMP3 is a critical mediator of Met-tRNA(i)(Met) transfer from methionyl-tRNA synthetase to eIF2 complex for the accurate and efficient translation initiation
Data show that aminoacyl-tRNA synthetase-interacting multifunctional protein-3 (AIMP3)/p18 is released from aminoacyl-tRNA synthetase-interacting multifunctional protein-3 (AIMP3) by UV irradiation-induced stress.
Decreased expression of AIMP3 in gastric and colorectal cancer tissues suggests that down-regulation of this protein may be related to inactivation of the tumor suppressor functions of AIMP proteins and might play a role in the development of GC and CRC.
p18 is a haploinsufficient tumor suppressor and a key factor for ATM/ATR-mediated p53 activation.

No EEF1E1 mutations were detected in human cancer specimens.
AIMP3 is a specific regulator of mature lamin A and imply that enhanced expression of AIMP3 might be a factor driving cellular and/or organismal aging [AIMP3]
This gene encodes a multifunctional protein that localizes to both the cytoplasm and nucleus. In the cytoplasm, the encoded protein is an auxiliary component of the macromolecular aminoacyl-tRNA synthase complex. However, its mouse homolog has been shown to translocate to the nucleus in response to DNA damage, and it plays a positive role in ATM/ATR-mediated p53 activation. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the neighboring downstream MUTED (muted homolog) gene. An EEF1E1-related pseudogene has been identified on chromosome 2.
