简介
The JAM-A/CD321 protein is critical for the formation of tight junctions in epithelial cells, participating in early junction development and recruiting PARD3. However, the formation of PARD6-PARD3 complex may hinder PARD3-JAM1 interaction, thus preventing tight junction assembly. JAM-A/CD321 Protein, Rat (HEK293, Fc) is the recombinant rat-derived JAM-A/CD321 protein, expressed by HEK293 , with C-hFc labeled tag.

Protein Description
JAM-A (Junctional Adhesion Molecule A), also known as CD321, is a cell adhesion molecule predominantly expressed in endothelial cells and immune cells. It plays a crucial role in maintaining the integrity of tight junctions in epithelial and endothelial barriers, regulating leukocyte transmigration, and contributing to various physiological and pathological processes, including inflammation, tumor metastasis, and tissue regeneration. The research surrounding JAM-A/CD321 has gained increasing interest due to its involvement in various diseases, such as cancer, autoimmune disorders, and cardiovascular diseases, where it can influence cell signaling and adhesion mechanisms. Additionally, the functional diversity of JAM-A is highlighted by its interactions with multiple binding partners, including integrins and other adhesion molecules, which modulate cell behavior and fate. The development of recombinant JAM-A proteins facilitates detailed studies of its structure-function relationship, underlying molecular mechanisms, and potential therapeutic applications. Understanding the biological roles of JAM-A/CD321 through recombinant protein studies may offer insights into novel therapeutic strategies targeting inflammatory and metastatic pathways, highlighting its significance in biomedical research and potential clinical interventions.
