| Biochem/physiol Actions: | KRAS (Kirsten rat sarcoma-2 virus oncogene) mutation has been associated with early rectal cancer and colorectal cancer. The protein has a role in signaling pathways. |
| Biochem/physiol Actions: | KRAS (kirsten rat sarcoma-2 virus oncogene) upon binding to a cell surface receptor, including EGFR functions as a self-inactivating signal transducer by cycling from GDP- to GTP-bound states. Mutation in the gene leads to poor prognosis of early rectal cancer. |

| General description: | c-K-Ras or KRAS (Kirsten rat sarcoma-2 virus oncogene) is a small GTP-binding protein. The gene encoding it is localized on human chromosome 12p12.1. KRAS has two splice variants, that is, KRASA and KRASB (KRAS proto-oncogenes). Expression of KRASA is restricted to specific tissues whereas KRASB is ubiquitously expressed. |
| General description: | This gene, a Kirsten ras oncogene homolog from the mammalian ras gene family, encodes a protein that is a member of the small GTPase superfamily. A single amino acid substitution is responsible for an activating mutation. The transforming protein that results is implicated in various malignancies, including lung adenocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma. Alternative splicing leads to variants encoding two isoforms that differ in the C-terminal region. (provided by RefSeq) |
