Recombinant PE-Labeled Human HLA-A*03:01&B2M&KRAS G12V (VVGAVGVGK) Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. PE-Labeled Human HLA-A*03:01&B2M&KRAS G12V (VVGAVGVGK) Tetramer is assembled by biotinylated monomer and PE-Labeled streptavidin. It contains Gly25-Thr305 (HLA-A*03:01), 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.
