Overview of Gene Research
NSUN3, also known as NOP2/Sun RNA methyltransferase 3, is a mitochondrial methyltransferase. It is crucial for initiating the 5-formylcytidine (f5C) modification in mitochondrial methionine tRNA anticodon, which is essential for the translation of the AUA codon in mammalian mitochondria. This modification is involved in mitochondrial function-related pathways, and is of great biological importance for embryonic development and normal physiological function of adult tissues [1,2,3].
Whole-body Nsun3 knockout in mice leads to embryonic death between E10.5 and E12.5, highlighting its essential role in embryonic development [1]. Heart-specific Nsun3 knockout (Nsun3HKO) mice show enlarged heart mitochondria with fragmented cristae, enhanced heart contraction, and age-associated mild heart enlargement. In Nsun3HKO hearts, the enzymatic activities of respiratory complexes decrease, despite no down-regulation of mitochondrial mRNAs encoding respiratory complex subunits [1].
In conclusion, NSUN3 is essential for mammalian embryonic development and normal mitochondrial function in adult tissues. Studies using Nsun3 KO and CKO mouse models have revealed its significance in embryonic development and heart-related pathologies, providing valuable insights into understanding the role of mitochondrial tRNA modification in these biological processes and associated diseases [1].
