[HTML][HTML] Calpain Cleavage Promotes Talin Binding to the β3Integrin Cytoplasmic Domain

B Yan, DA Calderwood, B Yaspan… - Journal of biological …, 2001 - ASBMB
Talin links integrin β cytoplasmic domains to the actin cytoskeleton and is involved in the
clustering and activation of these receptors. To understand how talin recognizes integrin β
cytoplasmic domains, we configured surface plasmon resonance methodology to measure
the interaction of talin with the β 3 integrin cytoplasmic domain. Here we report that the N-
terminal∼ 47-kDa talin head domain (talin-H) has a 6-fold higher binding affinity than intact
talin for the β 3 tail. The affinity difference is mainly due to a difference ink on. Calpain …
