ITGA5 (Integrin alpha 5) is a protein that plays a crucial role in cell adhesion, migration, and signaling. It is a transmembrane receptor that interacts with various extracellular matrix proteins, such as fibronectin, to regulate cell behavior.
ITGA5 has been shown to promote tumor growth, invasion, and metastasis by facilitating cell adhesion, migration, and angiogenesis.
ITGA5 is a gene that encodes for the alpha 5 subunit of the integrin alpha 5 beta 1 (α5β1) receptor. Integrins are a family of transmembrane receptors that play a crucial role in cell adhesion, migration, and signaling.
ITGA5 has been found to be overexpressed in various types of tumorsand its expression has been associated with poor prognosis.
Integrin α5β1 - Alpha-5 Beta-1 Integrin / Fibronectin Receptor
Abbreviation: α5β1, ITGA5/ITGB1, VLA-5
Type: Cell-surface adhesion receptor / integrin heterodimer
Function: Integrin α5β1 is composed of the ITGA5 and ITGB1 subunits and is the principal fibronectin receptor. It recognizes the RGD-containing region of fibronectin and regulates extracellular-matrix adhesion, fibronectin assembly, cytoskeletal organization, proliferation, migration, survival, angiogenesis, and FAK/Src/PI3K-AKT signaling.
Cancer: ↑ Frequently increased or functionally activated in cancer. α5β1 promotes tumor-cell adhesion, survival, migration, invasion, angiogenesis, metastatic dissemination, and interactions with tumor-associated extracellular matrix and stromal fibronectin.
