Investigations of plasma membrane particles in Saccharomyces cerevisiae protoplasts are shortly reviewed. Particle arrangement into a hexagonal patterns is considered to reflect some minute changes in the biomembrane organization rather than functional differentiation. Plasma membrane invaginations are proved to be rigid structures capable of migrating in the fluid domain of the membrane. Density of the particles per unit area is related to the degree of membrane stretching which suggest that upon membrane extension new protein molecules are shifted towards the hydrophobic layer of the membrane.
简要回顾了酿酒酵母原生质体中质膜颗粒的研究。颗粒排列成六边形模式被认为反映了生物膜组织中的一些微小变化，而非功能分化。已证明质膜内陷是能够在膜的流体区域迁移的刚性结构。单位面积颗粒的密度与膜拉伸程度相关，这表明在膜伸展时，新的蛋白质分子会向膜的疏水层移动。
