AsnRS is essential for protein translation and has been related to autoimmune and neurological diseases. Unlike its bacterial homologs, this protein has a conserved N-terminal extension (this entry) connected by an unstructured tether to the part of the enzyme that has homologues within eukaryotes and prokaryotes: an anticodon-binding domain (Pfam:PF01336), a hinge region (HR), and a catalytic domain (Pfam:PF00152). This domain folds into two alpha-helices and three beta-strands form a parallel/antiparallel mixed beta-sheet and has a characteristic lysine-rich helical motif that interacts with tRNA. It also shows chemokine activity through its interaction with C-C chemokine receptor 3 (CCR3) and the promotion of NRS-CCR3-mediated proinflammatory signaling [1-3].
