Protein Structure

UniProt Annotation

Function

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. {ECO:0000269PubMed:12060739, ECO:0000269PubMed:12819782, ECO:0000269PubMed:16135753, ECO:0000269PubMed:18695251}.

Subcellular Localization

Cytoplasm, cytosol {ECO:0000269PubMed:18695251}. Nucleus {ECO:0000269PubMed:18695251}. Note=Following DNA damage, dissociates from the aminoacyl-tRNA synthase complex and translocates from the cytoplasm to the nucleus.
