The researchers' findings are described in the March 27 issue of Science magazine. In the cover image, the cargo adaptor Bicaudal-D2 (orange) brings the dyein motor complex (yellow) together with its essential cofactor dynactin (red.) This giant complex of 37 proteins drags cellular cargos for long distances along microtubules (blue) Cryo-electron microscopy provides insight into the structural assembly and operation of this supracomplex. See page 1441.
