Did you know?
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… Webintegrin functions adhesion of cells to the substratum transmission of signals between outside and inside ________ are dynamic structures that anchor cells to their substratum …
