Comments:
NAT10 is the human homolog of yeast RRA1. It is a disease-associated gene (progeria, laminopathies). NAT10 is required for the formation of two ac4C in human SSU rRNA: one in helix 34, predicted, based on the yeast work, to map to position 1338, and one in helix 45, predicted to be at position 1843. siRNA-mediated depletion of NAT10 also leads to loss of tRNA acetylation. NAT10 interacts in vivo in human cells with THUMPD1, the homolog of TAN1, and a NAT10/THUMPD1 complex is suggested to work in tRNA acetylation in human, similar to the KRE33/TAN1 complex in budding yeast. NAT10 complements both 18S rRNA and tRNA acetylation in yeast.
