RRAS2（RAS related 2），癌症关联基因，基因ID：22800，这个基因编码ras样小gtpase的r-ras亚家族的一个成员。编码的蛋白质与质膜相结合，可能起信号转导的作用这种蛋白可能在激活控制细胞增殖的信号转导途径中发挥重要作用。这种基因的突变与某些肿瘤的生长有关。这个基因的假基因出现在1号和2号染色体上交替剪接导致多个转录变体。[由RefSeq提供，2010年4月]This gene encodes a member of the R-Ras subfamily of Ras-like small GTPases. The encoded protein associates with the plasma membrane and may function as a signal transducer. This protein may play an important role in activating signal transduction pathways that control cell proliferation. Mutations in this gene are associated with the growth of certain tumors. Pseudogenes of this gene are found on chromosomes 1 and 2. Alternate splicing results in multiple transcript variants. [provided by RefSeq， Apr 2010]。
