CD18

Integrin beta-2 (CD18) is a is_associated_with::protein that in humans is encoded by the ITGB2 is_associated_with::gene.

It is the beta subunit of four different structures:
 * is_associated_with::LFA-1 (paired with is_associated_with::CD11a)
 * is_associated_with::Macrophage-1 antigen (paired with is_associated_with::CD11b)
 * is_associated_with::Integrin alphaXbeta2 (paired with is_associated_with::CD11c)
 * is_associated_with::Integrin alphaDbeta2 (paired with is_associated_with::CD11d)

Interactions
CD18 has been shown to interact with is_associated_with::ICAM-1,  is_associated_with::FHL2, is_associated_with::PSCD1  and is_associated_with::GNB2L1.
