Introduction
Plectin is a multidomain protein with large size (>500kDa) and versatile binding properties, which abundantly expressed in a wide variety of mammalian tissues and cell types, combined with different binding partners. It has important roles in maintaining the mechanical stability of skin, skeletal muscle and heart [1].
Overall structure
Plectin can be divided in three main sections; a central coiled-coil rod domain, N and C-terminal globular region and exhibits a dumbbell like structure. C-terminal region is composed of 6 homologous repeating domains, and this region has a role in binding to intermediate filaments such as vimentin and cytokeratin [2]. N-terminal globular region contains actin binding domain (ABD) comprising two calponin homology () and .Image:Plectin structure.jpg (Litjens, 2006)
