信号受体内吞作用的功能结果由受体在降解和再循环途径之间的内体分选决定。受体如何有效地再循环,以序列依赖性的方式,这是不同于本体膜再循环,是未知的。在这里,在活细胞中,我们可视化的原型序列依赖性回收受体,β-2肾上腺素能受体,从散装回收蛋白质和降解δ-阿片受体的排序。我们的研究结果揭示了一个显着的多样性,在回收途径的水平上的个别内体,并表明,序列依赖性回收是一个积极的过程介导的不同的内体亚结构域不同的介导批量回收。我们确定了一个专门的子集内体上的管状微结构域,稳定的高度本地化的,但动态的肌动蛋白机械,介导这种排序,并提供证据表明,这些肌动蛋白稳定的结构域提供了物理基础的两步动力学和亲和力为基础的模型,蛋白质分选到序列依赖的回收途径。
The functional consequences of signaling receptor endocytosis are determined by the endosomal sorting of receptors between degradation and recycling pathways. How receptors recycle efficiently, in a sequence-dependent manner that is distinct from bulk membrane recycling, is not known. Here, in live cells, we visualize the sorting of a prototypical sequence-dependent recycling receptor, the beta-2 adrenergic receptor, from bulk recycling proteins and the degrading delta-opioid receptor. Our results reveal a remarkable diversity in recycling routes at the level of individual endosomes, and indicate that sequence-dependent recycling is an active process mediated by distinct endosomal sub-domains distinct from those mediating bulk recycling. We identify a specialized subset of tubular microdomains on endosomes, stabilized by a highly localized but dynamic actin machinery, that mediate this sorting, and provide evidence that these actin-stabilized domains provide the physical basis for a two-step kinetic and affinity-based model for protein sorting into the sequence-dependent recycling pathway.
