In mammalian cells, eight cytoplasmic aminoacyl-tRNA synthetases (AARS), and three non-synthetase proteins, reside in a large multi-tRNA synthetase complex (MSC). the MSC is suggested to be a super-complex of two identical, symmetrically arranged sub-units, each containing a single copy of the constituents, with the exception of LysRS which is present as a dimer in each sub-unit (Figure (Figure1B,1B, adapted from (27,28)). The sub-units are proposed to be joined by dimers of AspRS and the ProRS domain of GluProRS, and possibly by LysRS tetramers (20). Four AARSs containing GST-like domains important in protein-protein interactions form a MetRS-AIMP3–GluProRS–AIMP2 core of the complex (27,29). These proteins, together with AspRS, and possibly LeuRS and IleRS (30), form a distinct sub-complex denoted as sub-complex I (27). Sub-complex II consists of AIMP1, GlnRS, ArgRS, a dimer of LysRS, and AIMP2 (which is shared by both sub-complexes). |
