integrin

[in′teg·rən]
(cell molecular)
A heterodimeric transmembrane receptor protein of animal cells that binds to components of the extracellular matrix on the outside of a cell and to the cytoskeleton on the inside of the cell, functionally connecting the cell interior to its exterior; in blood cells, integrins are also involved in cell-cell adhesion.

The company is also pursuing independent development of nacellins against integrin alpha-4-beta-7 (IBD) and SMURF2 (fibrosis); its lead program seeks to develop orally bioavailable inhibitors of integrin alpha-4-beta-7, which are safer and less immunogenic than marketed and investigational biologics targeting the same protein.
When the outside part of the integrin molecule binds to the matrix, a signal is sent inside the cell via a G protein, a type of protein involved in cell signalling but that was not previously known to interact with integrins.
An introductory chapter on integrin biology sets the stage for further discussion of the role that integrins and associated proteins play in animal development; extracellular matrix assembly and cell migration (essential for organizing cells in tissues during embryogenesis and tissue repair); and regulation of intracellular signaling "cross-talk" cascades (that control cell differentiation and proliferation).
