VAMP8-3xHA Uptake Assay in HeLa Cells
Authors:  Steve Jean and Amy A. Kiger, date: 02/20/2016, view: 2564, Q&A: 0
Transmembrane proteins are rarely exclusively localized to a specific vesicle or an organelle. Most transmembrane proteins undergo complicated trafficking routes. Thus, transmembrane proteins are under constant flux, and at steady state, found on a ...
RAB21 Activity Assay Using GST-fused APPL1
Authors:  Steve Jean and Amy A. Kiger, date: 02/20/2016, view: 2623, Q&A: 0
The Rab family of small GTPases are essential regulators of membrane trafficking events. As with other small GTPase families, Rab GTPases cycle between an inactive GDP- bound state and an active GTP-bound state. Guanine nucleotide exchange factors ...

Synthetic Lethality Screens Using RNAi in Combination with CRISPR-based Knockout in Drosophila Cells
Authors:  Benjamin E. Housden, Hilary E. Nicholson and Norbert Perrimon, date: 02/05/2017, view: 2606, Q&A: 0
A synthetic lethal interaction is a type of genetic interaction where the disruption of either of two genes individually has little effect but their combined disruption is lethal. Knowledge of synthetic lethal interactions can allow for elucidation ...
