CDK5RAP1

Functionⁱ

Methylthiotransferase that catalyzes the conversion of N6-(dimethylallyl)adenosine (i₆A) to 2-methylthio-N6-(dimethylallyl)adenosine (ms₂i₆A) at position 37 (adjacent to the 3'-end of the anticodon) of four mitochondrial DNA-encoded tRNAs (Ser(UCN), Phe, Tyr and Trp) (PubMed:22422838, PubMed:25738458, PubMed:28981754).

Essential for efficient and highly accurate protein translation by the ribosome (PubMed:22422838, PubMed:25738458, PubMed:28981754).

Specifically inhibits CDK5 activation by CDK5R1 (PubMed:11882646).

Essential for efficient mitochondrial protein synthesis and respiratory chain; shows pathological consequences in mitochondrial disease (PubMed:25738458).

Caution

CDK5RAP1 was proposed to act on both nuclear and mitochondrial RNA (PubMed:22422838). However, another study shows that ms2i6A is a mitochondrial tRNA specific modification and is absent from nuclear encoded RNA species, implying that there is no methylthiotransferase activity on nuclear RNA (PubMed:28981754).2 Publications
