The unfolded protein response represses nitrogen-starvation induced developmental differentiation in yeast

Article Abstract:

The unfolded protein response (UPR) has been found to repress, in yeast, nitrogen-starvation-induced developmental differentiation. High translation rates in a nitrogen-rich environment likely are coupled to limited protein unfolding in the endoplasmic reticulum (ER) and likely activate the UPR thereby.

Mediator function of the human Rad52B-Rad51C complex in RAd51/RPA-catalyzed DNA strand exchange

Article Abstract:

The stoichiometric complex of the human rad51B and Rad51C proteins has been found to be able to partially overcome the suppressive effect of hRPA on hRAD51-catalyzed DNA pairing and strand exchange. They can thus identify the Rad51B-Rad51C complex as a mediator of recombination. The proteins are homologs of the Saccharomyces cerevisiae Rad55 and Rad57 proteins,
