Acta Crystallogr Sect F Struct Biol Cryst Commun. 2011 Jun 1;67(Pt 6):696-9. doi: 10.1107/S1744309111013820. Epub 2011 May 26.

Abstract

Kindlins contribute to the correct assembly of integrin-containing focal adhesion sites through their direct interaction with the cytoplasmic tail of β-integrin. The FERM domain of kindlins has a unique subdomain organization: the F2 subdomain harbours a centrally located pleckstrin homology (PH) domain that is thought to be involved in the membrane targeting of kindlins. FERM domains are found in a number of cytoskeletal proteins that mediate the interaction between integrins and cytosolic proteins. In the present study, the PH domain of human kindlin-2 was subcloned, solubly expressed in Escherichia coli and crystallized using the hanging-drop vapour-diffusion method. A diffraction data set was collected at 2.8 Å resolution using synchrotron radiation on BL-4A at the Pohang Accelerator Laboratory (Pohang, Republic of Korea).
