ERBB is abbreviated from erythroblastic oncogene B, a gene originally isolated from the avian genome. The human protein is also frequently referred to as HER2 (human epidermal growth factor receptor 2) or CD340 (cluster of differentiation 340). [5] [6] [7] HER2 is a member of the human epidermal growth factor receptor (HER/EGFR/ERBB) family ...
All four ErbB receptor family members are nearly same in the structure having single-chain of modular glycoproteins. [4] This structure is made up of an extracellular region or ectodomain or ligand binding region that contains approximately 620 amino acids, a single transmembrane-spanning region containing approximately 23 residues, and an intracellular cytoplasmic tyrosine kinase domain ...
The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). In many cancer types, mutations affecting EGFR expression or activity could result in cancer. [6]
A cutaneous receptor is a sensory receptor found in the skin that provides information about temperature, touch (including vibration and pain), spatial orientation,pressure (stretching or squeezing), and metabolic circumstances (including those induced by external chemical substances).
Cancers without hormone receptors at all are known as HR negative. Additionally, doctors have been able to examine cancer cells for the HER2 gene, and cancers with too many copies of the HER2 gene ...
The HER2 gene (also known as HER2/neu and ErbB2 gene) is amplified in 20–30% of early-stage breast cancers. [44] Trastuzumab is a monoclonal antibody targeting HER2, inducing an immune-mediated response that causes internalization and recycling of HER2. It may also upregulate cell cycle inhibitors such as p21 Waf1 and p27 Kip1. [58]
