Molecular cloning of Drosophila mus308, a gene involved in DNA cross-link repair with homology to prokaryotic DNA polymerase I genes.

abstract：:Fusions between the TRM1 gene of Saccharomyces cerevisiae and COXIV or DHFR were made to examine the mitochondrial targeting signals of N2,N2-dimethylguanosine-specific tRNA methyltransferase [tRNA (m2(2)G)dimethyltransferase]. This enzyme is responsible for the modification of both mitochondrial and cytoplasmic tRNAs...

Cells overexpressing Rac2 and PLD2 simultaneously show a robust initial (<10 min) response toward a chemoattractant that is later (>30 min) greatly diminished over PLD2-only controls. The first phase is due to the presence of a Rac2-PLD2 p...
