NHE-1 is a ubiquitous, mitogen-activatable, mammalian Na+/H+ exchanger that maintains cytosolic pH and regulates cell volume. We have previously shown that the kinetics of NHE-1 positive cooperative activation by intracellular acidifications fit best with a Monod-Wyman-Changeux mechanism, in which a dimeric NHE-1 oscillates between a low- and a...

Cisplatin is an antineoplastic drug, mostly documented to cause cell death through the formation of DNA adducts. In patients, it exhibits a range of short-term side effects that are unlikely to be related to its genomic action. As cisplatin has been shown to modify membrane properties in different cell systems, we investigated its effects on...
The shelterin proteins protect telomeres against activation of the DNA damage checkpoints and recombinational repair. We show here that a dimer of the shelterin subunit TRF2 wraps ∼ 90 bp of DNA through several lysine and arginine residues localized around its homodimerization domain. The expression of a wrapping-deficient TRF2 mutant, named...
