Tumour prevention by a single antibody domain targeting the interaction of signal transduction proteins with RAS.
description:
Epitope residues are calculated from the structure [PDB: 2UZI] as the antigen residues at 4 Å
distance from the antibody.
The epitope-specific anti-RAS scFv#6 intrabody bound to activated HRAS-GTP(gammaS) with high affinity. The single VH#6 domain (iDab#6) without the VL domain had an affinity of KD = 6.2 nM (k on = 2.93 x 105 and k off = 1.82 x 10-3). Anti-RAS does not bind to HRAS-GDP.
