Preferred Label : integrin alpha chains;
MeSH definition : The alpha subunits of integrin heterodimers (INTEGRINS), which mediate ligand specificity.
There are approximately 18 different alpha chains, exhibiting great sequence diversity;
several chains are also spliced into alternative isoforms. They possess a long extracellular
portion (1200 amino acids) containing a MIDAS (metal ion-dependent adhesion site)
motif, and seven 60-amino acid tandem repeats, the last 4 of which form EF HAND MOTIFS.
The intracellular portion is short with the exception of INTEGRIN ALPHA4.;
MeSH synonym : alpha chains, integrin; integrin alpha subunits; alpha integrins; integrins, alpha;
