Summaries for ITGAE Gene

Entrez Gene Summary for ITGAE Gene

  • Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This gene encodes an I-domain-containing alpha integrin that undergoes post-translational cleavage in the extracellular domain, yielding disulfide-linked heavy and light chains. In combination with the beta 7 integrin, this protein forms the E-cadherin binding integrin known as the human mucosal lymphocyte-1 antigen. This protein is preferentially expressed in human intestinal intraepithelial lymphocytes (IEL), and in addition to a role in adhesion, it may serve as an accessory molecule for IEL activation.

GeneCards Summary for ITGAE Gene

ITGAE (Integrin Subunit Alpha E) is a Protein Coding gene. Diseases associated with ITGAE include hairy cell leukemia and splenic marginal zone lymphoma. Among its related pathways are Sertoli-Sertoli Cell Junction Dynamics and Degradation of the extracellular matrix. An important paralog of this gene is ITGA8.

UniProtKB/Swiss-Prot for ITGAE Gene

  • Integrin alpha-E/beta-7 is a receptor for E-cadherin. It mediates adhesion of intra-epithelial T-lymphocytes to epithelial cell monolayers.
