Descriptions

Kindlin-3 is a member of the kindlin family of focal adhesion proteins which bind to integrin beta-chain cytoplasmic domains to regulate integrin function. kindlin-3 is maintained in a homotrimer state, which is different from the monomer that binds integrin β cytoplasmic tails. The trimer formation of kindlin-3 results in an autoinhibited state, as the integrin-binding pocket is blocked by the pleckstrin homology (PH) domain of another protomer. Mutations disrupting the trimer interface (Q471A, A475F, S478A) lead to increased integrin-mediated cell adhesion and spreading, indicating relief from autoinhibition. This autoinhibition regulates kindlin-3’s role in integrin activation and signaling, with implications for diseases like leukocyte adhesion deficiency (LAD) III and cancer.

Name Definition
integrin binding Binding to an integrin.

8 GO annotations of biological process

Name Definition
cell-matrix adhesion The binding of a cell to the extracellular matrix via adhesion molecules.
integrin activation The aggregation, arrangement and bonding together of an integrin, a heterodimeric adhesion receptor formed by the non-covalent association of particular alpha and beta subunits, that lead to the increased affinity of the integrin for its extracellular ligands.
integrin-mediated signaling pathway The series of molecular signals initiated by an extracellular ligand binding to an integrin on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription.
leukocyte cell-cell adhesion The attachment of a leukocyte to another cell via adhesion molecules.
platelet aggregation The adhesion of one platelet to one or more other platelets via adhesion molecules.
positive regulation of cell migration Any process that activates or increases the frequency, rate or extent of cell migration.
regulation of cell-cell adhesion mediated by integrin Any process that modulates the frequency, rate, or extent of cell-cell adhesion mediated by integrin.
substrate adhesion-dependent cell spreading The morphogenetic process that results in flattening of a cell as a consequence of its adhesion to a substrate.
