Integrins are obligate heterodimers composed of α and β subunits. Several genes code for multiple isoforms of these subunits, which gives rise to an array of unique integrins with varied activity. In mammals, integrins are assembled from eighteen α and eight β subunits, in Drosophila five α and two β subunits, and in Caenorhabditis nematodes two α subunits and one β subunit. The α and β subunits are both class I transmembrane proteins, so each penetrates the plasma membrane o… WebJun 15, 2004 · In their resting state, integrins normally bind the molecules that activate them with low affinity.

WebIntegrin αvβ3 is one of the 24 heterodimeric structural proteins of the plasma membrane of animal cells. The extracellular domain of αvβ3 comprises about 80% of its mass and is devoted largely to interactions with extracellular matrix (ECM) proteins, such as vitronectin and fibronectin, and cell-cell interaction. WebMar 30, 2024 · Integrin β7 is also expressed in normal lymphocytes at low levels, but adopts the inactive conformation. Thus, MMG49 rarely binds to normal lymphocytes. In addition, integrin β7 is not expressed in non-hematopoietic tissues. These results suggest that the MMG49 antigen is a good therapeutic target for MM.
