N. Gupta-Rossi et al., "Monoubiquitination and endocytosis direct γ-secretase cleavage of activated Notch receptor,"
This paper is important because it shows that the Notch receptor must be monoubiquitinated and endocytosed before it can be cleaved by presenilin/γ-secretase, a key step in Notch activation .... These findings contradict a previous study claiming that endocytosis is dispensable for signaling by such Notch forms.
C. Wiesmann et al., "Allosteric inhibition of protein tyrosine phosphatase 1B,"
An inhibitor for protein tyrosine phosphatase 1B (PTP-1B) was found to bind 20 Ångstroms away from the active site. It was still active as an inhibitor, however, because it stabilized the open-enzyme conformation, preventing the enzyme from closing ...
