The crystal structure of the Kinesin-5 BASS domain tetramer: (A) Side view of the crystal structure of the KLP61F BASS tetramer (residues 640–796 shown) colored in rainbow, starting with N-termini in blue traversing to C-termini in red, respectively. Four monomers pack as anti-parallel pairs of anti-parallel coiled-coil dimers. (B) shows the BASS structure rotated 90° around the filament axis relative to panel A. The dimensions of the BASS tetramer bundle structure are shown. (C) Side view of the BASS tetramer, with two BASS anti-parallel dimers colored in blue and red, respectively. (D) Detailed interaction between two monomers in the BASS anti-parallel dimer. (E) A 60° rotated view of D. - See more at: http://elifesciences.org/content/3/e02217#sthash.9VMjrUdO.dpuf

LET-99 is a G-protein regulator that localizes to the presumptive site of cleavage. YFP::LET-99 localization through cytokinesis of a one-cell C.elegans embryo. The image has been pseudo-colored to show the range of YFP::LET-99. Brighter represents greater protein localization.

C. elegans male germ cells: Top, gonad dissected out of worm stained with RAD51 recombinase (green), chromatin mark, H3K9me2 (red) to mark the X chromosome, and DAPI (DNA, blue) . Bottom, individual cells from different germline stages: left, mitosis (tubulin, green; CENPA, red; DAPI, blue); middle, meiotic prophase (pachytene): top, aligned homologous chromosomes (synaptonemal complex, red and green; DAPI, blue); bottom, nuclear pore complex (yellow) and DAPI (blue) and right, the meiosis I division (tubulin, green; membrane protein, red; DAPI, blue).

Superresolution (SIM) imaging of yeast cells defective for mitochondrial division expressing mitochondrial-targeted DsRed (mito-DsRED) and ER-targeted GFP (GFP-HDEL.

Electron tomography of integrin configuration on the limiting membrane of SAOS-α2β1 cells. The missing wedge effect of ET has been resolved to achieve the isotropic resolution in all dimensions of the structures. This allows the tracking of the distribution of α2-integrin in an endosome intracellularly.
