Functional Studies - PP3, Negative control for PP2 (AB120617)

ab11512 staining E cadherin in SW480 cells treated with PP3 (ab120617), by ICC/IF. No change of E cadherin expression with increased concentration of PP3 is observed, as described in literature, since PP3 is the negative control for PP2.
The cells were incubated at 37°C for 24h in media containing different concentrations of ab120617 (PP3) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab11512 (5 μg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-rat polyclonal antibody (ab98386) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

Supplementary information

EGFR also known as epidermal growth factor receptor is a membrane-bound protein with a mass of approximately 170 kDa. It is expressed in many cell types including epithelial tissues. EGFR has tyrosine kinase activity and plays an important role in the regulation of cell growth and differentiation. PI4K2B PI4 kinase beta also known as PI4KB shares a similar functional landscape. With a mass of about 92 kDa PI4KB localizes mainly in the cytoplasm and trans-Golgi network and participates in phosphatidylinositol (PI) phosphorylation converting PI to phosphatidylinositol 4-phosphate (PI4P). PI4K2A has a function similar to PI4KB in lipid-mediated signaling.
Biological function summary

EGFR participates in signal transduction cascades that promote cellular proliferation and survival. It often forms homodimers or heterodimers with other receptors in the cell membrane upon ligand binding. PI4K2B acting within lipid microdomains regulates membrane trafficking and assignation of signaling proteins to various cell functions. It does not necessarily work alone and could be a component of larger protein complexes that control phosphorylation dynamics. Both PI4KB and PI4K2A have recognized roles in the maintenance of PI4P levels within cells affecting vesicular trafficking.

Pathways

EGFR primarily associates with the MAPK and PI3K-Akt signaling pathways influencing cell cycle progression and apoptosis. Key interactions with proteins such as Src enhance downstream signaling and functional outcomes. PI4K2B and PI4KB integrate into pathways that involve phosphatidylinositol metabolism playing roles alongside proteins such as PIP kinase and serving as important nodes in PI3P-related pathways. These connections influence cellular trafficking and organelle function.

EGFR overexpression or mutations relate to cancers notably lung cancer and glioblastoma through altered signaling pathways resulting in unchecked cell division. Its interaction with Src renders it a target for inhibitors like PP2 Src inhibitors in therapeutic investigations. PI4KB dysregulation associates with neurological diseases where disruptions in PI4P balance affect neurodegenerative disease progression. Therefore EGFR and PI4K enzymes are linked to cancer and neurological disorders where their pathways intertwine with disease-specific alterations in protein networks.
