- Ncl1-mediated metabolic rewiring critical during metabolic stress
Accumulation of cysteine induces translational defects and metabolic rewiring that are abrogated by leucine in a transfer RNA (tRNA) methyltransferase NCL1-dependent manner in yeast.
- Human DNA polymerase delta is a pentameric holoenzyme with a dimeric p12 subunit
The subunit p12 of human DNA polymerase delta (hPolδ) can dimerize, facilitating its interaction with PCNA and suggesting that hPolδ exists in a pentameric form in the cell.
- Chemical genetic identification of GAK substrates reveals its role in regulating Na+/K+-ATPase
Novel GAK phosphorylation targets are identified using chemical genetic methods. One of the substrates is the α subunit of the Na+/K+-ATPase, phosphorylation of which is necessary for its surface trafficking from endosomes. Conserved functions of NAK family kinases are described.
