Description
Bhagyashree Dasari Rao and Snezhana Oliferenko compare the cell membranes of two related fission yeast species whose membrane fats differ sharply. Their study came out in 2026. Membrane electrical properties shape how the proteins embedded in them behave.
One species builds membranes from mostly unsaturated fats plus the standard fungal sterol. The other uses many saturated fats with an unusual short chain, plus a bacterial-style sterol mimic gained by gene transfer. Using fluorescent dyes that report on the membrane environment, the pair found similar overall polarity in both species. Yet the second species showed a higher dipole potential, an internal voltage of the membrane. Mutant and model membrane tests pointed to its sterol and its saturated fats as the support. Membrane character emerges from the whole lipid mix, not single ingredients.
