FERMT3

Kindlins are a small family of proteins that mediate protein-protein interactions involved in integrin activation and thereby have a role in cell adhesion, migration, differentiation, and proliferation. The protein encoded by this gene has a key role in the regulation of hemostasis and thrombosis. This protein may also help maintain the membrane skeleton of erythrocytes. Mutations in this gene cause the autosomal recessive leukocyte adhesion deficiency syndrome-III (LAD-III). Alternative splicing results in multiple transcript variants encoding distinct isoforms.

Fermitin Family Member 3

Plays a central role in cell adhesion in hematopoietic cells (PubMed:19234463, PubMed:26359933).

Acts by activating the integrin beta-1-3 (ITGB1, ITGB2 and ITGB3) (By similarity).

Required for integrin-mediated platelet adhesion and leukocyte adhesion to endothelial cells (PubMed:19234460).

Required for activation of integrin beta-2 (ITGB2) in polymorphonuclear granulocytes (PMNs) (By similarity).

Podosome. Present in the F-actin surrounding ring structure of podosomes, which are specialized adhesion structures of hematopoietic cells.

Leukocyte adhesion deficiency 3 (LAD3):
A disorder characterized by recurrent bacterial infections without pus formation, leukocytosis and major bleeding disorders.
