这个基因编码一种属于泛素特异性加工蛋白酶家族的蛋白质编码蛋白被认为是通过蛋白质在细胞器上的泛素化来调节内体的形态，并参与内体早期的货物分类和膜运输。这种蛋白质是细胞进入细胞周期s期所必需的，在发育过程中也是hedgehog信号通路中的一个正调节因子。这个基因的假基因存在于2号和6号染色体上交替剪接导致多个转录变体。[由RefSeq提供，2013年9月]
This gene encodes a protein that belongs to the ubiquitin-specific processing protease family of proteins. The encoded protein is thought to regulate the morphology of the endosome by ubiquitination of proteins on this organelle and is involved in cargo sorting and membrane trafficking at the early endosome stage. This protein is required for the cell to enter the S phase of the cell cycle and also functions as a positive regulator in the Hedgehog signaling pathway in development. Pseudogenes of this gene are present on chromosomes 2 and 6. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
