Recombinant Biotinylated Human HLA-A*11:01&B2M&KRAS G12V (VVGAVGVGK) Monomer Protein is expressed from E.coli with His tag and Avi tag at the C-Terminus.It contains Gly25-Thr305(HLA-A*11:01), Ile21-Met119(B2M) and VVGAVGVGK peptide. Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) is the most commonly mutated oncogene in human cancer. The developments of many cancers depend on sustained expression and signaling of KRAS, which makes KRAS a high-priority therapeutic target. The virtual screening approach to discover novel KRAS inhibitors and synthetic lethality interactors of KRAS are discussed in detail.
