ran是ras超家族的一种小的gtp结合蛋白,与核膜相关,被认为通过与其他蛋白的相互作用来控制多种细胞功能。这个基因编码一个非常大的ran结合蛋白,免疫定位到核孔复合体。该蛋白是一个巨大的支架和嵌合体亲环素相关的核孔蛋白参与了ran-gtpase循环。编码蛋白直接与E2酶UBC9相互作用,并强烈促进SUMO1从UBC9转移到SUMO1靶点SP100。这些发现将sumoylation定位于核孔复合体的细胞质丝,并表明,对于某些底物,修饰和核导入是相互关联的事件。该基因在位于染色体2q重组热点的基因簇中部分复制。[由RefSeq提供,2008年7月]
RAN is a small GTP-binding protein of the RAS superfamily that is associated with the nuclear membrane and is thought to control a variety of cellular functions through its interactions with other proteins. This gene encodes a very large RAN-binding protein that immunolocalizes to the nuclear pore complex. The protein is a giant scaffold and mosaic cyclophilin-related nucleoporin implicated in the Ran-GTPase cycle. The encoded protein directly interacts with the E2 enzyme UBC9 and strongly enhances SUMO1 transfer from UBC9 to the SUMO1 target SP100. These findings place sumoylation at the cytoplasmic filaments of the nuclear pore complex and suggest that, for some substrates, modification and nuclear import are linked events. This gene is partially duplicated in a gene cluster that lies in a hot spot for recombination on chromosome 2q. [provided by RefSeq, Jul 2008]
