Description générale

c-K-Ras or KRAS (kirsten rat sarcoma-2 virus oncogene) is a small GTP-binding protein. It is located on human chromosome 12p12.1. KRAS has two splice variants, such as KRASA and KRASB (KRAS proto-oncogenes). Expression of KRASA is restricted to specific tissues whereas KRASB is expressed everywhere .

Spécificité

The antibody reacts with c-K-Ras and v-K-Ras p21. It crossreacts with cH-Ras and cN-Ras p21 on immunoblots.

Immunogène

recombinant p21 protein

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)

Actions biochimiques/physiologiques

KRAS (kirsten rat sarcoma-2 virus oncogene) mutation leads to poor prognosis of early rectal cancer.

Although the protooncogenes small GTPases Ras are redox-sensitive proteins, how they are regulated by redox signaling in the central nervous system (CNS) is still poorly understood. Alteration in redox-sensitive targets by redox signaling may have myriad effects on Ras stability
