EGFR

ErbB1/HER1 receptor tyrosine kinase; EGF binding activates RAS-ERK, PI3K-Akt, and STAT3. Mutated or amplified in NSCLC, glioblastoma, HNSCC, and CRC. Targeted by gefitinib/erlotinib (EGFR-mutant NSCLC) and cetuximab (KRAS-WT CRC, HNSCC); osimertinib overcomes T790M resistance.

Also known as: ErbB1, HER1, epidermal growth factor receptor, ERBB1, EGF receptor
