8. Wild type Nir2, but not its mutants, restores PI(4,5)P2 levels at
the PM of Nir2-depleted cells
Kim. et al, EMBO Reports 2013
Nir2 is an upstream regulator of key phosphoinositide pathways in
mammalian cells: the PI3K/AKT and MAPK pathways
Editor's Notes
only a small subset of PH domains in the human genome are thought to bind PIP3 with high affinity and specificity (10–20% out of 290 PH domains have been shown to robustly bind phosphoi-nositides, with some of these robustly binding PI-3,4-P2 or PI-4,5-P2 but not PIP3) [9,10]. Of the PH domain-containing proteins that do bind PIP3, the serine/threo-nine AGC-family protein kinase AKT has received the greatest attention, especially for its multi-faceted roles in promoting glucose metabolism and cancer
