ITGB3（integrin subunit beta 3），癌症关联基因，基因ID：3690，itgb3蛋白产物是整合素β链β3。整合素是由α链和β链组成的完整的细胞表面蛋白。一个给定的链可以与多个伙伴结合，产生不同的整合素。整合素β3与血小板中的αiib链一起被发现。整合素参与细胞粘附和细胞表面介导的信号传导。[由RefSeq提供，2008年7月]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. [provided by RefSeq， Jul 2008]。
