Actin-binding domain of mouse plectin. Crystal structure and binding to vimentin

Popis výsledku v původním jazyce

Plectin, a large and widely expressed cytolinker protein, is composed of several subdomains that harbor binding sites for a variety of different interaction partners. A canonical actin-binding domain (ABD) comprising two calponin homology domains (CH1 and CH2) is located in proximity to its amino terminus. However, the ABD of plectin is unique among actin-binding proteins as it is expressed in the form of distinct, plectin isoform-specific versions. We have determined the three-dimensional structure oftwo distinct crystalline forms of one of its ABD versions (pleABD/2alpha) from mouse, to a resolution of 1.95 and 2.0 A. Comparison of pleABD/2alpha with the ABDs of fimbrin and utrophin revealed structural similarity between plectin and fimbrin, although the proteins share only low sequence identity. In fact, pleABD/2alpha has been found to have the same compact fold as the human plectin ABD and the fimbrin ABD, differing from the open conformation described for the ABDs of utrophin and
