Receptor tyrosine-protein kinase erbB-2 is a protein that normally resides in the membranes of cells and is encoded by the ERBB2 gene. ERBB is abbreviated from erythroblastic oncogene B, a gene originally isolated from the avian genome.

In humans, the family includes Her1 (EGFR, ErbB1), Her2 (ErbB2), Her3 (ErbB3), and Her4 (ErbB4). The gene symbol, ErbB, is derived from the name of a viral oncogene to which these receptors are homologous: erythroblastic leukemia viral oncogene.

Mar 30, 2025 · ERBB2 (Erb-B2 Receptor Tyrosine Kinase 2) is a Protein Coding gene. Diseases associated with ERBB2 include Visceral Neuropathy, Familial, 2, Autosomal Recessive and Glioma Susceptibility 1. Among its related pathways are Drug-mediated inhibition of ERBB2 signaling and Signaling by ERBB2 KD Mutants.

Considering the current impetus to deliver molecularly targeted treatments for cancer, a better understanding of the therapeutic potential of ERBB2 mutations is needed. This article reviews the distribution of ERBB2 mutations in different tumor types, focusing on potential as a …

The erbB2 (also known as HER2 or neu) gene encodes a 185-kDa transmembrane glycoprotein, which belongs to the epidermal growth factor receptor (EGFR) family. ErbB2 is a receptor tyrosine kinase with intrinsic tyrosine kinase activity.

Canonical ErbB-2 isoform and ErbB-2 variant c located in the nucleus drive triple negative breast cancer growth. Targetable ERBB2 mutation status is an independent marker of adverse prognosis in estrogen receptor positive, ERBB2 non-amplified primary lobular breast carcinoma: a retrospective in silico analysis of public datasets.

May 4, 2020 · ErbB2 amplification or overexpression is observed in ~25–30% of breast cancers [1] and is associated with an aggressive clinical phenotype. In vitro studies have shown that ErbB2/ErbB3...

ERBB2 (v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2, also known as HER2 and neu) is a gene that encodes for the receptor tyrosine-protein kinase erbB-2. ERBB2 has been found to be amplified with an increased copy number in several cancers (PMID: 20185938).

Here we review the distribution of ERBB2 mutations in different tumor types, their potential as a novel biomarker that defines new subsets in many cancers, and current data on preclinical and clinical efforts to target these mutations.

ErbB (also termed HER) receptors are expressed in various tissues of epithelial, mesenchymal and neuronal origin, in which they are involved in the control of diverse biological processes such as proliferation, differentiation, migration and apoptosis.
