Gene: [21q223/ITGB2] integrin, beta 2 (antigen CD18B (p95); LFA1-beta; LCAM-B); cell adhesion molecule, leukocyte, beta (light chain; LCAM-B); lymphocyte function-associated antigen 1, beta subunit (LCAM-B); complement component receptor 3, beta (beta 2 integrin; CD18; LCAM-B); immunodeficiency LFA1-beta (leukocyte adhesion deficiency; MIM:116920); [CD18 GP90 ]
FUN | Beta-2 integrin determines the adhesive properties of leukocyte cell surface." |
MOP | Beta-2 integrin (94 kD) is a component of three leukocyte glycoproteins, which function is cell adhesion. These are: complement component receptor 3 (Mac-1; GEM:16p112/ITGAM), protein p150,95 (GEM:16p121/ITGAX), and LFA1-alpha (GEM:16p123/ITGAL). The three proteins differ in alpha subunits, which are noncovalently bound (one to three molecules) to beta-2 integrin and assigned to alpha integrins." |
PAT | Beta-2 integrin deficiency (identified by the coincident deficiency of three glycoprotein complexes, LFA-1, Mac-1 (CR3), and p150,95) manifest itself as recurrent bacterial and fungous infections. At least five recessive variants of leukocyte adhesion defects, accounted for by mutant beta peptide inability to associate with alpha peptides, have been identified." |
PRO | Probe J-9 contains a 2.8 kb cDNA insert; the clone has been obtained by scrinning U937 library, activated with phorbol ether." |
