epidermal growth factor

Epidermal Growth Factor binds to epidermal growth factor receptor (EGFR) and stimulates cell growth and proliferation. It is approved for the treatment of diabetic foot ulcers.

The epidermal growth factor receptor is the cell-surface receptor for members of the epidermal growth factor family of extracellular protein ligands.

Epidermal Growth Factor Receptor Peptide Acetate exists on the cell surface and is activated by the binding of its specific ligands.EGFR belongs to the ErbB family of receptor tyrosine kinases (RTK).

[pTyr5] EGFR (988-993) TFA, derived from the Tyr992 autophosphorylation site of the epidermal growth factor receptor (EGFR 988-993), often complexes with catalytically inactive protein-tyrosine phosphate 1B (PTP1B) [1].

EGFR peptide (myristoylated), a synthetic peptide inhibitor of PKC (IC50 = 5 µM), corresponds to the intracellular region's amino acid sequence of EGFR. It effectively reverses doxorubicin resistance in UV-2237M (UV-2237M-ADRR) fibrosarcoma cells at a concentration of 1 µM.

EGFRvIII peptide, a synthetic peptide mirroring the EGFRvIII fusion junction—a tumor-specific, perpetually active EGFR variant missing amino acids 6-273 of the wild-type—binds to HLA-A*0201-positive T2 cells under MHC class I at 25 µg/ml. It enables antigen presentation in dendritic cells from human peripheral blood mononuclear cells (PBMCs), thus activating CD8+ cytotoxic T lymphocytes and prompting IFN-γ production. Administered at 15 µg/animal with the TLR5 agonist flagellin B, EGFRvIII peptide elevates CD8+ T cell numbers, lowers regulatory T cells (Tregs) in the brain, diminishes tumor volume, and extends survival in a GL261 glioblastoma mouse model.

Affibody (affibody) ligands that are specific for the extracellular domain of human epidermal growth factor receptor 2 (HER2/neu) have been selected by phage display technology from a combinatorial protein library based on the 58 amino acid residue staphy

HER2 neu (654-662) GP2 acetate is derived from the human epidermal growth factor receptor 2 (HER2-Neu, 654–662). HER2 neu (654-662) GP2 acetate induces HLA-A2-restricted cytotoxic T lymphocytes reactive to various epithelial cancers.

[pTyr5] EGFR (988-993) is a compound derived from the auto-phosphorylation site Tyr992 in the epidermal growth factor receptor (EGFR 988-993), and it is often associated with the catalytically inactive protein-tyrosine phosphatase 1B (PTP1B).
