Title
The tracjectories of JF549–PI(4,5)P2 from colocalization of EGFR and PIP2 in living cells after EGF stimulation
Description
Time-lapse images of Halo-PI(4,5)P_{2} ( Halo-PLCdelta-PH) on HeLa cells between 1 and 5 min after EGF (epidermal growth factor) stimulation.
To simultaneously observe the dynamics of both EGFR(epidermal growth factor receptor) molecules and PI(4,5)P_{2} (phosphatidylinositol-4,5-bisphosphate) molecules upon EGF stimulation, EGFR-GFP and Halo-PI(4,5)P_{2} were imaged using dual-color total internal reflection (TIRF) microscopy. Halo-PI(4,5)P_{2} was visualized with JF549, a HaloTag ligand. This dataset includes only Halo-PI(4,5)P_{2} images.
The images of EGFR-GFP detected by GFP were deposited in another dataset in this project; Fig3A_EGFR_after_EGF.

Description
Halo-PLCdelta-PH, which serves as a reporter for PI(4,5)P_{2}, was labeled with Janelia Fluor 549 (JF549) after the expression of EGFR-GFP and Halo-PLCdelta-PH fusion proteins in EGFR-knockout (KO) HeLa cells.
MeSH
Phosphatidylinositol 4,5-Diphosphate (
D019269)
Intrinsic Variable
The endogenous EGFR in HeLa cells was knocked out by using CRISPR/Cas9 gene editing.
Extrinsic Variable
EGFR-GFP and Halo-PLCdelta-PH were expressed exogenously. Ten nM Janelia Fluor 549 (JF549), a HaloTag ligand was added to visualize Halo–tagged PLCdelta–PH.
