VTN (Vitronectin)

Introduction

Vitronectin (VTN) is a multifunctional extracellular matrix glycoprotein found in plasma and tissues. It plays important roles in cell adhesion, migration, and immune regulation. In the brain, vitronectin is involved in synaptic function and has been implicated in Alzheimer's disease through its interactions with [Aβ](/proteins/amyloid-beta) and its role in microglial phagocytosis.
