Alpha-v beta-3

From Wikipedia, the free encyclopedia
Jump to: navigation, search

αVβ3 is a type of integrin that is a receptor for vitronectin.[1] It consists of two components, integrin alpha V and integrin beta 3 (CD61), and is expressed by platelets. Furthermore, it is a receptor for phagocytosis on macrophages or dendritic cells.[2]

As a drug target[edit]

Integrin αVβ3 is potential drug target because abnormal expression of v3 is linked to the development and progression of various diseases.[3]

Inhibitors like etaracizumab may be used as antiangiogenics.

One novel protein (ProAgio) has been designed to bind at an unusual site, and then induces apoptosis by recruiting caspase 8.[3]
