我们讨论了整合素簇(和其他类似的膜蛋白)在带有皮质细胞骨架的细胞膜上的扩散。我们认为,与被迫一次穿过细胞骨架屏障的正常低聚物不同,蛋白质簇本质上应该被视为多条腿的随机行走者,可以通过一条腿一次穿过围栏来穿过细胞骨架屏障。我们给出了描述这一现象的数学模型,它导致了一个应该适用于任何团簇大小的双参数扩散模型。我们还在红细胞模型系统中对这种影响进行了数值模拟和讨论。
We discuss the diffusion of clusters of integrins (and other similar membrane proteins) on a cell membrane with a cortical cytoskeleton. We argue that protein clusters—in contrast with normal oligomers, which are forced to pass through cytoskeletal barriers all at once—should be treated essentially as many-legged random walkers that can pass through a cytoskeletal barrier by putting one leg at a time through the fence. We present the mathematics that should describe the phenomenon, which result in a two-parameter model of diffusion that should apply to any cluster size. We also perform and discuss numerical simulations of the effect in the erythrocyte model system.
