Prm1 prevents contact-dependent lysis of yeast mating pairs.

Abstract excerpt

Membrane fusion requires localized destabilization of two phospholipid bilayers, but unrestrained membrane destabilization could result in lysis. prm1 mutant yeast cells have a defect at the plasma membrane fusion stage of mating that typically results in the accumulation of prezygotes that have fingers of membrane-bound cytoplasm projecting from one cell of each pair into its mating partner in the direction of...
