What's a GeneRIF?

one out of two cytosolic lysine tRNAs of the yeast Saccharomyces cerevisiae is partially internalized by mitochondria. The key protein factor of this process is the precursor of mitochondrial lysyl-tRNA synthetase, preMsk1p.
Title: Procedure for Purification of Recombinant preMsk1p from E. coli Determines Its Properties as a Factor of tRNA Import into Yeast Mitochondria.
In this work, the authors identify the hinge region with two adjacent helices H5 and H7 of preMSK1 to be responsible for mitochondrial targeting of the tRNA(Lys) and characterize preMsk1p versions with altered tRK1 import capacities.
Title: tRNA mitochondrial import in yeast: Mapping of the import determinants in the carrier protein, the precursor of mitochondrial lysyl-tRNA synthetase.
