AlaRS (968 amino acids, 106.7 kDa), Alanine-tRNA ligase, is an important enzyme that catalyzes addition of alanine to tRNA in protein synthesis, utilizing ATP hydrolysis. AlaRS contains three domains; the N-terminal catalytic domain, the editing domain and the C-terminal C-Ala domain. Also edits incorrectly charged tRNA(Ala) via its editing domain.

Fig.2 Immunofluorescence staining of AlaRS protein in HeLa cells by using anti-AlaRS antibody. The cells were fixed with 4% paraformaldehyde and permeabilized with 0.25% TritonX100. The antibody was used at 1/100 dilution. As the second antibody, AF488 conjugated goat anti-rabbit IgG antibody was used at 1/1,000 dilution. Nuclear DNA was stained with DAPI (left) and the merged image was shown in the center.
