Human ERBB3/HER3 HEK293T Stable Cell Line

Introduction

Human ERBB3/HER3 is a transmembrane receptor tyrosine kinase that belongs to the epidermal growth factor receptor (EGFR) family. It is encoded by the ERBB3 gene and is expressed in a variety of tissues, including the heart, brain, and breast. ERBB3 plays a crucial role in cell proliferation, survival, and differentiation. Dysregulation of ERBB3 has been linked to various diseases, including cancer, making it a promising therapeutic target.

Structure of Human ERBB3/HER3

The human ERBB3 protein consists of 1342 amino acids and is composed of several domains, including an extracellular ligand-binding domain, a transmembrane domain, and an intracellular tyrosine kinase domain. The extracellular domain is responsible for binding to ligands, such as neuregulins, while the intracellular domain is involved in downstream signaling pathways.

Activity of Human ERBB3/HER3

ERBB3 is activated by binding to its ligands, which leads to dimerization with other members of the EGFR family, such as ERBB2/HER2. This dimerization results in the activation of the tyrosine kinase domain and the initiation of downstream signaling cascades, including the PI3K/AKT and MAPK pathways. These pathways play a crucial role in cell growth, survival, and differentiation.

Application of Human ERBB3/HER3 HEK293T Stable Cell Line

The Human ERBB3/HER3 HEK293T Stable Cell Line is a valuable tool for studying the role of ERBB3 in various cellular processes and for drug discovery and development. This cell line is generated by stably transfecting the HEK293T cell line with the human ERBB3 gene, resulting in the overexpression of ERBB3 on the cell surface.

One of the main applications of this stable cell line is in flow cytometry, a technique used to analyze the expression of cell surface proteins. The overexpression of ERBB3 in this cell line allows for easy detection and quantification of the receptor, making it a useful tool for studying the expression and activation of ERBB3 in different cell types and under different conditions.

Moreover, the Human ERBB3/HER3 HEK293T Stable Cell Line is a valuable model for studying the role of ERBB3 in cancer. Dysregulation of ERBB3 has been implicated in various types of cancer, including breast, lung, and ovarian cancer. This cell line can be used to investigate the effect of targeting ERBB3 in cancer cells and to identify potential therapeutic agents that can inhibit its activity.

In addition, the stable overexpression of ERBB3 in this cell line makes it a suitable model for drug screening and development. The activation of ERBB3 leads to the activation of downstream signaling pathways, making it a potential therapeutic target for various diseases. By using this cell line, researchers can screen for compounds that can modulate the activity of ERBB3 and potentially develop new treatments for diseases associated with its dysregulation.
