Drugging Ras GTPase: a comprehensive mechanistic and signaling structural view
S Lu, H Jang, S Gu, J Zhang, R Nussinov - Chemical Society Reviews, 2016 - pubs.rsc.org
Ras proteins are small GTPases, cycling between inactive GDP-bound and active GTP-
bound states. Through these switches they regulate signaling that controls cell growth and …

Membrane-associated Ras dimers are isoform-specific: K-Ras dimers differ from H-Ras dimers
Are the dimer structures of active Ras isoforms similar? This question is significant since Ras
can activate its effectors as a monomer; however, as a dimer, it promotes Raf's activation …
