ICAMs normally functions to promote intercellular adhesion and signalling. However, The N-terminal domain of the receptor binds to the rhinovirus 'canyon' surrounding the icosahedral 5-fold axes, during the viral attachment process [1]. This family is a family that is part of the Ig superfamily and is therefore related to the family ig (Pfam:PF00047).	Domain
