A comprehensive and quantitative interactome of RAS


ABSTRACT: We investigated a comprehensive and quantitative interactome of RAS, a protein found to be a driver of many human cancers. This resource identifies interactors of the active form of RAS (nucleotide-dependent) as well as isoform-specific (KRAS, HRAS, and NRAS) interactors of RAS. Several of the proteins identified were confirmed as being important for cancer cell viability and senescence.

Active mutations in the RAS genes are found in ∼30% of human cancers. Although thought to have overlapping functions, RAS isoforms show preferential activation in human tumors, which prompted us to employ a comparative and quantitative proteomics approach to generate isoform-specific and nucleotide-dependent interactomes of the four RAS isoforms, KRAS4A, KRAS4B, HRAS, and NRAS. Many isoform-specific interacting proteins were identified, including HRAS-specific CARM1 and CHK1 and KRAS-specific PI  ...[more]
