Aminoacyl tRNA synthase complex-interacting multifunctional protein 2

Gene

Aimp2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Required for assembly and stability of the aminoacyl-tRNA synthase complex. 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.4 Publications

Pathology & Biotechi

Disruption phenotypei

Reduced levels of component enzymes and associated factors of the aminoacyl-tRNA synthase complex, lack of complex formation and lethality within two days of birth. Neonates display severe hyperplasia in a number of organs including lung, intestine and liver, lung failure, and disturbed thymocyte proliferation and differentiation. Embryonic fibroblasts deficient in Aimp2 are resistant to apoptosis following UV irradiation.2 Publications

Interactioni

Subunit structurei

Component of the aminoacyl-tRNA synthase complex which is comprised of a bifunctional glutamyl-prolyl-tRNA synthase, the monospecific isoleucyl, leucyl, glutaminyl, methionyl, lysyl, arginyl and aspartyl-tRNA synthases, and three auxiliary proteins, EEF1E1/p18, AIMP2/p38 and AIMP1/p43. 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 KARS and PARK2/parkin (via first RING-type domain) (By similarity).By similarity

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
