Proximity Label-MS

An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.

Auxin-induced depletion of human CCR4-NOT subunits reveals opposing functions of CNOT1 and CNOT4 in mRNA metabolism.

CCR4-NOT regulates multiple steps in gene regulation, including transcription, mRNA decay, protein ubiquitylation, and translation. Originally discovered in yeast, this complex is highly conserved across eukaryotes, although its composition and functions differ between mammals and yeast. For example, unlike yeast Not4, human CNOT4 (E3 Ubiquitin Ligase) does not form a stable complex with CCR4-NOT, and its functions are less clear ... [more]
