CRYSTAL STRUCTURE OF HRAS(G12V)- ANTI-RAS FV COMPLEX

OverviewOverview

Many disease-related processes occur via protein complexes that are, considered undruggable with small molecules. An example is RAS, which is, frequently mutated in cancer and contributes to initiation and maintenance, of the disease by constitutive signal transduction through protein, interaction with effector proteins, like PI3K, RAF and RALGDS. Such, protein interactions are therefore significant targets for therapy. We, describe a single immunoglobulin variable region domain that specifically, binds to activated GTP-bound RAS and prevents RAS-dependent tumorigenesis, in a mouse model. The crystal structure of the immunoglobulin-RAS complex, shows that the variable region competitively binds to the conformationally, variant regions of RAS, where its signalling effector molecules ...
