Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Snx4-assisted vacuolar targeting of transcription factors defines a new autophagy pathway for controlling ATG expression.

Hanley SE, Willis SD, Cooper KF

Autophagy, in part, is controlled by the repression and activation of autophagy-related (ATG) genes. Here, we describe a new selective autophagy pathway that targets functional transcriptional regulators to control their activity. This pathway is activated in response to nitrogen starvation and recycles transcriptional activators (Msn2 and Rim15) and a repressor (Ssn2/Med13) of ATG expression. Further analysis of Ssn2/Med13 vacuolar proteolysis ... [more]
