Objective Defects of DNA damage response(DDR)will result in genome instability and drive carcinogenesis.Proteins carrying BRCA1 C Terminus(BRCT)domains have evolved to response and resolve DNA damage.
Objective Background: Ubiquitin-ligase Fbw7 can induce degradation of many proto-oncogenes and suppress tumor.This aim of the study was to investigate mutations and mechanisms of inactivation of Fbw7
Objective A number of guanine nucleotide exchange factors(GEFs)including cell transforming factor ECT2 are believed to drive carcinogenesis through activating distinct oncogenic GTPases.
