Affinity Capture-Western

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 identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

Hypoxia inactivates the VHL tumor suppressor through PIASy-mediated SUMO modification.

Cai Q, Verma SC, Kumar P, Ma M, Robertson ES

The hypoxic microenvironment contributes to embryonic development and tumor progression through stabilization of the potent transcriptional factor HIFalpha. In normoxia, the tumor suppressor protein VHL acts as an E3 ubiquitin ligase to target HIFalpha for proteolytic destruction. Increasing evidence shows that VHL is a multifunctional adaptor involved in inhibition of HIFalpha-dependent and independent cellular processes. However, the molecular effect of ... [more]
