PRKN（parkin RBR E3 ubiquitin protein ligase），癌症关联基因，基因ID：5071，该基因的确切功能尚不清楚；然而，编码蛋白是多蛋白e3泛素连接酶复合物的一个组成部分，该复合物介导了蛋白酶体降解的底物蛋白的靶向性。已知该基因突变可导致帕金森病和常染色体隐性遗传青少年帕金森病。该基因的选择性剪接产生编码不同亚型的多个转录变体。该基因的其他剪接变体已被描述，但目前缺乏转录支持。[由RefSeq提供，2008年7月]The precise function of this gene is unknown; however， the encoded protein is a component of a multiprotein E3 ubiquitin ligase complex that mediates the targeting of substrate proteins for proteasomal degradation. Mutations in this gene are known to cause Parkinson disease and autosomal recessive juvenile Parkinson disease. Alternative splicing of this gene produces multiple transcript variants encoding distinct isoforms. Additional splice variants of this gene have been described but currently lack transcript support.
