Integrin subunits span the cell membrane and have short cytoplasmic domains of 40–70 amino acids. The exception is the beta-4 subunit, which has a cytoplasmic domain of 1,088 amino acids, one of …

By recruiting several proteins that bind actin filaments, the cytoplasmic tails mediate the integrin-cytoskeletal connection, which is essential for most, if not all, integrin mediated functions (see below …

Jan 2, 2023 · Integrin functions are dependable on a delicate balance between active and inactive status via multiple mechanisms, including protein-protein interactions, conformational changes, and trafficking.

Aug 23, 2025 · Each integrin is composed of two different protein chains, an alpha (α) and a beta (β) subunit, forming a functional heterodimer. Many alpha and beta subunits exist, and specific …

Nov 30, 2023 · The integrin family of proteins consists of alpha and beta subtypes, which form transmembrane heterodimers. Integrins function as adhesion receptors for extracellular ligands and …

Integrin receptors are composed of two polypeptides that each pass through the membrane once. As one might expect from an actin-linked structure, focal adhesions and their in vivo equivalents are …

The term integrin was originally suggested to describe membrane receptors that “integrate” the extracellular environment (matrix or other cells) with the intracellular cytoskeleton. At present, 18 α- …

Sep 28, 2022 · Dr. Hynes coined the term “integrin” for these wonderfully complicated molecules that “integrate” the extracellular matrix with the intracellular environment (the cytoskeleton, in particular).

Results from the initial studies investigating integrin-mediated adhesion and migration led to the hypothesis that integrin activation simply occurred when an integrin receptor came into contact with …

Oct 7, 2020 · This review presents current evidence from human and animal studies on integrin structure and molecular signaling, with particular emphasis on signal transduction in infants.
