ITGAL - integrin subunit alpha L Gene
Also Known as CD11A; LFA-1; LFA1A
Species: Homo sapiens
About ITGAL
This gene has 22 transcripts (splice variants), 138 orthologues and 17 paralogues. Biased expression in lymph node (RPKM 36.8), spleen (RPKM 35.7) and 11 other tissues.
Summary
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]
