Sign Up to like & getrecommendations! Published in 2022 at "Advanced Science"
DOI: 10.1002/advs.202202448
Abstract: The guanine nucleotide exchange factor (GEF) SOS1 catalyzes the exchange of GDP for GTP on RAS. However, regulation of the GEF activity remains elusive. Here, the authors report that PPDPF functions as an important regulator… read more here.

DOI: 10.1021/acs.jmedchem.2c01300
Abstract: Direct blockade of KRAS driver mutations in colorectal cancer (CRC) has been challenging. Targeting SOS1, a guanine nucleotide exchange factor, has arisen as an attractive approach for KRAS-mutant CRC. Here, we describe the development of… read more here.

DOI: 10.1073/pnas.1812963116
Abstract: Significance Mutants of RAS are major oncogenes and occur in many human cancers, but efforts to develop drugs that directly inhibit the corresponding constitutively active RAS proteins have failed so far. We therefore focused on… read more here.
