Gene: ITGB3

Alternate names for this Gene: BDPLT16|BDPLT2|CD61|GP3A|GPIIIa|GT

Gene Summary: The ITGB3 protein product is the integrin beta chain beta 3. Integrins are integral cell-surface proteins composed of an alpha chain and a beta chain. A given chain may combine with multiple partners resulting in different integrins. Integrin beta 3 is found along with the alpha IIb chain in platelets. Integrins are known to participate in cell adhesion as well as cell-surface mediated signalling.
