'''Structures of two intermediate filament-binding fragments of desmoplakin reveal a unique repeat motif structure'''<br />
'''Structures of two intermediate filament-binding fragments of desmoplakin reveal a unique repeat motif structure'''<br />


==Overview==
==Overview==
Desmosomes are intercellular junctions in which cadherin cell adhesion, molecules are linked to the intermediate filament (IF) system. Desmoplakin, is a member of the plakin family of IF-binding proteins. The C-terminal, domain of desmoplakin (DPCT) mediates binding to IFs in desmosomes. The, DPCT sequence contains three regions, termed A, B and C, consisting of 4.5, copies of a 38-amino acid repeat motif. We demonstrate that these regions, form discrete subdomains that bind to IFs and report the crystal, structures of domains B and C. In contrast to the elongated structures, formed by other kinds of repeat motifs, the plakin repeats form a globular, structure with a unique fold. A conserved basic groove found on the domain, may represent an IF-binding site.
