| + | [https://www.uniprot.org/uniprot/ITA1_HUMAN ITA1_HUMAN] Integrin alpha-1/beta-1 is a receptor for laminin and collagen. It recognizes the proline-hydroxylated sequence G-F-P-G-E-R in collagen. | ||

| + | Integrin proteins are very important adhesion receptors that mediate cell-cell and cell-extracellular matrix interactions. They play essential roles in cell signaling and the regulation of cellular shape, motility, and the cell cycle. Here, the transmembrane and cytoplasmic (TMC) domains of integrin alpha1 and beta1 were over-expressed and purified in detergent micelles. The structure and backbone relaxations of alpha1-TMC in LDAO micelles were determined and analyzed using solution NMR. A long helix, extending from the transmembrane region to the cytoplasmic tail, was observed in alpha1-TMC. Structural comparisons of alpha1-TMC with reported alphaIIb-TMC domains indicated different conformations in the transmembrane regions and cytoplasmic tails. An NMR titration experiment indicated weak interactions between alpha1-TMC and beta1-TMC through several alpha1-TMC residues located at its N-terminal juxta-transmembrane region and C-terminal extended helix region. | ||
