Integrin beta-2 (CD18) is a protein that in humans is encoded by the ITGB2 gene. It is the beta subunit of four different structures: LFA-1 (paired with CD11a) Macrophage-1 antigen (paired with CD11b) Integrin alphaXbeta2 (paired with CD11c) Integrin alphaDbeta2 (paired with CD11d)The ITGB2 protein product is the integrin beta chain beta 2. Integrins are integral cell-surface proteins composed of an alpha chain and a beta chain.
