Title
The tracjectories of EGFR-GFP from colocalization of EGFR and PI(4,5)P2 in living cells after EGF stimulation
Description
Time-lapse images of EGFR-GFP (EGF receptor tagged with GFP) on HeLa cells between 1 and 5 min after EGF (epidermal growth factor) stimulation.
To simultaneously observe the dynamics of both EGFR molecules and PI(4,5)P_{2} (phosphatidylinositol-4,5-bisphosphate) molecules upon EGF stimulation, EGFR-GFP and Halo-PI(4,5)P_{2} ( Halo-PLCdelta-PH) 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 EGFR-GFP images.
The images of Halo-PI(4,5)P_{2} detected by JF549 fluorescence were deposited in another dataset in this project; Fig3A_PIP2_after_EGF. ダイカンサｔウワタｓｈイカクｔオ

Description
The cytoplasmic tail of regulation of epidermal growth factor receptor (EGFR) was labeled with an enhanced green fluorescent protein (EGFR-GFP) and expressed in EGFR-knockout (KO) HeLa cells at low levels.

MeSH
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.
