Opto-PIP3
Construct PatternOpto-PIP3 is an optogenetic construct used to elevate or spatially pattern PI(3,4,5)P3 signaling in cells. In adipocytes, its activation largely mimicked the maximal effect of insulin on IRAP-pHluorin translocation, supporting the sufficiency of PI3K-generated PIP3 for much of this membrane-trafficking response.
