Kindlin-3 in the Immune System

Am J Clin Exp Immunol. 2014 Feb 27;3(1):37-42. eCollection 2014.


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. In contrast to kindlin-1 and kindlin-2 proteins, kindlin-3 is expressed mainly in the hematopoietic system. Mutations in kindlin-3 result in the rare genetic disorder, leukocyte adhesion deficiency type III (LAD-III), which is characterized by bleeding and recurrent infections due to deficient beta1, beta2 and beta3 integrin activation in platelets and leukocytes. Here, we review the role of kindlin-3 in integrin activation and in different immune cell functions.

Keywords: Kindlin; LAD-III; T cell; adhesion; integrin.
