function:ICAM proteins are ligands for the leukocyte adhesion protein LFA-1 (integrin alpha-L/beta-2). ICAM4 is also a ligand for alpha-4/beta-1 and alpha-V integrins.,online information:Blood group antigen gene mutation database,polymorphism:Responsible for the Landsteiner-Wiener blood group system. The molecular basis of the LW(A)=LW5/LW(B)=LW7 blood group antigens is a single variation in position 100; Gln-100 corresponds to LW(A) and Arg-100 to LW(B).,PTM:N- and O-glycosylated.,similarity:Belongs to the immunoglobulin superfamily. ICAM family.,similarity:Contains 2 Ig-like C2-type (immunoglobulin-like) domains.,tissue specificity:Erythrocytes.,
[Isoform Long]: Cell membrane; Single-pass type I membrane protein.; [Isoform Short]: Secreted .; Cell membrane ; Single-pass type I membrane protein .
Erythrocytes.
