Microfibrillar-associated Protein 4 Protein

Background

MFAP4 is a glycoprotein that plays a key role in the structural organization and function of the extracellular matrix (ECM), particularly in tissues requiring elasticity such as blood vessels, lungs, and skin. It interacts with elastin and fibrillin-containing microfibrils to support elastic fiber assembly and stability, contributing to tissue elasticity and resilience. Beyond its structural role, MFAP4 has been implicated in mediating cellular adhesion and interactions with integrins, influencing cell migration and repair processes. Additionally, MFAP4 is being explored as a biomarker for various diseases, including fibrotic disorders, cardiovascular conditions, and liver fibrosis. Current research continues to elucidate its involvement in ECM-related pathologies and its potential as a therapeutic target for diseases linked to compromised ECM integrity.
