Where are HER2 receptors found in the body?
The HER2 receptor is a 1255 amino acid, 185 kD transmembrane glycoprotein located at the long arm of human chromosome 17 (17q12) [6].
Is HER2/neu a receptor?
The HER2 gene makes HER2 proteins (also sometimes referred to as HER2/neu proteins). HER2 proteins are receptors on breast cells.
What type of receptor is HER2?
HER2 belongs to the human epidermal growth factor receptor family, which includes EGFR (alias HER1), HER3, and HER4. HER2 works as an oncogene in several cancers including breast cancers, manifesting its effect of carcinogenesis mainly by overexpression or due to gene amplification.
What do HER2 receptors do?
HER2 is a membrane tyrosine kinase and oncogene that is overexpressed and gene amplified in about 20% of breast cancers. When activated it provides the cell with potent proliferative and anti-apoptosis signals and it is the major driver of tumor development and progression for this subset of breast cancer.
What does Neu stand for in HER2 neu?
Name. HER2 is so named because it has a similar structure to human epidermal growth factor receptor, or HER1. Neu is so named because it was derived from a rodent glioblastoma cell line, a type of neural tumor.
What is HER2/neu gene?
Listen to pronunciation. A protein involved in normal cell growth. HER2/neu may be made in larger than normal amounts by some types of cancer cells, including breast, ovarian, bladder, pancreatic, and stomach cancers. This may cause cancer cells to grow more quickly and spread to other parts of the body.
What is HER2/neu meaning?
What is HER2/neu test for?
A laboratory test that measures the amount of HER2/neu protein on cancer cells or how many copies of the HER2/neu gene are in the DNA of cancer cells. The HER2/neu protein helps control normal cell growth.
What does neu positive mean?
If your cancer is HER2/neu positive, you may respond to a specific medicine that targets HER2/neu receptors. Results for IHC: A score of 0 or +1 means your tumor is HER2 negative. A score of +2 means the results are unclear and FISH testing should be done. A score of +3 means the tumor is HER2 positive.
What does HER2/neu positive mean?
HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2). This protein promotes the growth of cancer cells. In about 1 of every 5 breast cancers, the cancer cells have extra copies of the gene that makes the HER2 protein.
What does Neu mean?

What is HER2/neu negative?
Listen to pronunciation. (… NEH-guh-tiv) Describes cells that have a small amount or none of a protein called HER2 on their surface.

What is the name of the HER2 receptor?
In physiological conditions, this gene encodes a glycoprotein with molecular mass of 185 kDa (p185), named HER2 receptor or HER2 protein. HER2 and three structurally related tyrosine kinase receptors—HER1 (epidermal growth factor receptor (EGFR)), HER3 (ErbB3) and HER4 (ErbB4)—constitute the ErbB family.
What is the HER2/neu gene?
The HER2/neu gene is one of the family of genes encoding transmembrane receptors for four growth factors, including the epidermal growth factor receptor (EGFR), HER2/neu, HER3, and HER4.
What does HER2 positive and HER2 negative mean?
A score of 0 or +1 means your tumor is HER2 negative. A score of +2 means the results are unclear and FISH testing should be done. A score of +3 means the tumor is HER2 positive. FISH results are positive or negative.
Is the Her-2/neu proto-oncogene homologous to the epidermal growth factor receptor?
The HER-2/neu proto-oncogene is homologous with, but distinct from, the epidermal growth factor receptor.
