Entrez Gene Summary for RRAS2 Gene

  • 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]

GeneCards Summary for RRAS2 Gene

RRAS2 (Related RAS Viral (R-Ras) Oncogene Homolog 2) is a Protein Coding gene. Diseases associated with RRAS2 include teratocarcinoma and ovarian cancer, somatic. Among its related pathways are MAPK signaling pathway and GPCR Pathway. GO annotations related to this gene include GTP binding and GTPase activity. An important paralog of this gene is HRAS.

UniProtKB/Swiss-Prot for RRAS2 Gene

  • It is a plasma membrane-associated GTP-binding protein with GTPase activity. Might transduce growth inhibitory signals across the cell membrane, exerting its effect through an effector shared with the Ras proteins but in an antagonistic fashion

Disorders for RRAS2 Gene


  • Ovarian cancer (OC) [MIM:167000]: The term ovarian cancer defines malignancies originating from ovarian tissue. Although many histologic types of ovarian tumors have been described, epithelial ovarian carcinoma is the most common form. Ovarian cancers are often asymptomatic and the recognized signs and symptoms, even of late-stage disease, are vague. Consequently, most patients are diagnosed with advanced disease. {ECO:0000269 PubMed:8052619}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
