Kindlin-2 is a regulator for heterodimeric integrin adhesion receptors promotes integrin activation. Activation depends on binding of the N-terminal domain to the integrin beta cytoplasmic tail (CT), which disrupts the receptors association with alpha-CT and triggers the conformational transitions in the receptor. K2-N contains a conserved positively charged surface that binds to membrane enriched with negatively charged phosphatidylinositol-(4,5)-bisphosphate (PIP2). K2-N is also very similar to the homologous kindlin-1 F0 [1].

Integrins are ubiquitously expressed and are heterodimeric, each composed of an alpha and beta subunit. Several variations of the the alpha and beta subunits exist, and association of different alpha and beta subunits can have different a different binding specificity. This domain corresponds to the cytoplasmic domain of the beta subunit.
