ESCRT复合物的相互作用对内体运输至关重要。我们确定了对这一过程具有潜在意义的两个领域。MABP结构域存在于后生动物ESCRT-I/MVB12亚基、蛋白质分选调节剂Crag和细菌成孔蛋白中,可能介导运输过程中新的膜相互作用。在MVB12和UBAP1中发现的UBAP1-MVB12相关UMA结构域定义了一种新的适配器,可能会招募不同的ESCRT-I靶点。联系方式:aravind@ncbi.nlm.nih.gov补充信息:补充数据请访问ftp://ftp.ncbi.nih.gov/pub/aravind/UMA/MVB12.html。
Interactions of the ESCRT complexes are critical for endosomal trafficking. We identify two domains with potential significance for this process. The MABP domain present in metazoan ESCRT-I/MVB12 subunits, Crag, a regulator of protein sorting, and bacterial pore-forming proteins might mediate novel membrane interactions in trafficking. The UBAP1-MVB12-associated UMA domain found in MVB12 and UBAP1 defines a novel adaptor that might recruit diverse targets to ESCRT-I.
