From mutational inactivation to aberrant gain‐of‐function: unraveling the structural basis of mutant p53 oncogenic transition

FA Olotu, MES Soliman - Journal of Cellular Biochemistry, 2018 - Wiley Online Library
Various evidence has revealed that mutations in p53 exert activities that go beyond simply
inactivation of wildtype functions but rather elicits downstream interactions that promote …

Analysis of egg white protein composition with double nanohole optical tweezers

N Hacohen, CJX Ip, R Gordon - ACS omega, 2018 - ACS Publications
We use a double nanohole optical tweezer to analyze the protein composition of egg white
