Summaries for ITGAL Gene

Entrez Gene Summary for ITGAL Gene

  • ITGAL encodes the integrin alpha L chain. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This I-domain containing alpha integrin combines with the beta 2 chain (ITGB2) to form the integrin lymphocyte function-associated antigen-1 (LFA-1), which is expressed on all leukocytes. LFA-1 plays a central role in leukocyte intercellular adhesion through interactions with its ligands, ICAMs 1-3 (intercellular adhesion molecules 1 through 3), and also functions in lymphocyte costimulatory signaling. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for ITGAL Gene

ITGAL (Integrin, Alpha L (Antigen CD11A (P180), Lymphocyte Function-Associated Antigen 1; Alpha Polypeptide)) is a Protein Coding gene. Diseases associated with ITGAL include benign cephalic histiocytosis and cutaneous necrotizing vasculitis. Among its related pathways are Ras signaling pathway and Regulation of actin cytoskeleton. GO annotations related to this gene include cell adhesion molecule binding. An important paralog of this gene is ITGA8.
