DEPDC5（DEP domain containing 5， GATOR1 subcomplex subunit），癌症关联基因，基因ID：9681，该基因编码参与G蛋白信号通路的IML1蛋白家族成员雷帕霉素复合物1（mtorc1）途径的机制靶点通过感知营养物质的有效性来调节细胞生长。该基因编码的蛋白质是GATOR1（Rags的GAP活性）复合物的一个组成部分，它抑制mTORC1通路的氨基酸敏感分支该基因突变与常染色体显性遗传家族性变灶性局灶性癫痫有关。该基因内含子的单核苷酸多态性与慢性丙型肝炎病毒感染者肝癌风险增加有关。选择性剪接导致多个转录变体[由RefSeq提供，2014年3月]This gene encodes a member of the IML1 family of proteins involved in G-protein signaling pathways. The mechanistic target of rapamycin complex 1 (mTORC1) pathway regulates cell growth by sensing the availability of nutrients. The protein encoded by this gene is a component of the GATOR1 (GAP activity toward Rags) complex which inhibits the amino acid-sensing branch of the mTORC1 pathway. Mutations in this gene are associated with autosomal dominant familial focal epilepsy with variable foci. A single nucleotide polymorphism in an intron of this gene has been associated with an increased risk of hepatocellular carcinoma in individuals with chro。
