Summary

Automatic Translation

Automatic Translation

Here, we describe a methodology to perform a targeted siRNA “ubiquitome” screen to identify novel ubiquitin and ubiquitin-like regulators of the HIF1A-mediated cellular response to hypoxia.  This can be adapted to any biological pathway where a robust read out of reporter activity is available.
