Depositor Comments

Note1:
At the 5' of the IARS2 insert, we use different restriction enzymes for the insert and the backbone. Xho I for pcDNA3.1 (-) and Sal I for IARS2 ORF. The Xho I and Sal I share a compatible cohesive end. Ligation between the compatible cohesive ends generated by different enzymes destroy the 5' restriction site. We use this cloning method because that IARS2 ORF (ENST00000366922.3) bears intrinsic Xho I site.

Note2:
The IARS2 ORF is long, so we used additional primers (5'->3') for sanger sequencing as follow:
pc3.1-IARS2-P1: tgggaagtatgaagccaaacagt
pc3.1-IARS2-P2: gaccatggcaaaaggaacgg
pc3.1-IARS2-P3: caacagccaaaccactgagc
pc3.1-IARS2-P4: tgctcaatgctgccagaga

Note3:
The Flag tag in this plasmid was not tested in wenstern blot in the article because the IARS2 antibody is good enough.
