Integrin alpha X

From WikiMD's Wellness Encyclopedia

Integrin alpha X (ITGAX) is a protein that in humans is encoded by the ITGAX gene. It is also commonly referred to as CD11c. This protein is a type of integrin, a large family of proteins that mediate cell-to-cell and cell-to-extracellular matrix interactions.

Function[edit | edit source]

Integrin alpha X is a receptor for fibrinogen, factor X, and ICAM proteins. It recognizes the sequence G-P-R in fibrinogen. It mediates cell-cell interaction during inflammatory responses. It is especially important in monocyte adhesion and chemotaxis.

Structure[edit | edit source]

The ITGAX protein is a type I membrane protein found on the surface of cells. It is composed of two subunits, alpha and beta, which combine to form a heterodimer. The alpha X subunit is unique to ITGAX, while the beta subunit is shared with other integrins.

Clinical significance[edit | edit source]

Alterations in the ITGAX gene have been associated with various diseases, including glomerulonephritis, a type of kidney disease, and leukemia, a type of cancer. It is also involved in the immune response to infections and inflammation.

Research[edit | edit source]

Research into ITGAX is ongoing, with studies focusing on its role in immune response, cell adhesion, and disease progression. It is also being investigated as a potential target for drug therapies.
