26494905 two non-syndromic retinitis pigmentosa pedigrees with segregating mutations in TRNT1
25958396 The discriminator base represents an important substrate recognition element for tRNA nucleotidyltransferases.
25849199 A model of action is proposed, where motif C forms a flexible spring element modulating the relative orientation of the enzyme's head and body domains to accommodate the growing 3'-end of the tRNA.
25652405 The clinical phenotypes associated with TRNT1 mutations are largely due to impaired mitochondrial translation, resulting from defective CCA addition to mitochondrial tRNA(Ser(AGY)).
25640237 Tandem CCA addition is not the result of a modified enzymatic activity that is particular to unstable RNAs. Rather, it is a consequence of the natural activity of the CCA-adding enzyme on a substrate with increased conformational flexibility, the CCA-adding enzyme is able to trigger the degradation of potentially detrimental small RNAs and tRNAs.
25193871 The patient-associated TRNT1 mutations result in partial loss of function of TRNT1 and lead to metabolic defects in both the mitochondria and cytosol, which can account for the phenotypic pleiotropy.

18575231 is a RNA polymerase which newly adds CCA sequence to tRNA 3'terminal. This reaction was named as Vice-Anchored Knock-in and Lock Dynamics.[review]
17204286 These findings strongly suggest that the splice variant of the human CCA-adding enzyme is expressed in the cell although the in vivo function remains unclear.
12729736 The crystal structure reveals a four domain architecture with a cluster of conserved residues forming a positively charged cleft between the first two domains.
