Comparing the relative similarity of cellular molecules to alternate templates allows classification of related complexes in the cell using fewer particles than needed for 3D classification and is more practicable for low abundance complexes.
Histone variant H2A.Z is deposited near transcription start sites by the chromatin remodeler SWR1 and seems to be removed by RNA polymerase II at an early stage of transcription elongation.

In triple-layered rotavirus particles, strong interaction between the external and middle layers provides high mechanical strength for protection tasks, while weaker interaction between the middle and inner layers favors transcription.
Building on previous work (Bai et al., 2013), we describe an algorithm that allows cryo-EM structure determination to near-atomic resolution for protein complexes as small as 170 kDa.

Building on previous work in cryo-electron microscopy (Entchev et al, 2015), it shown that a combination of the Volta phase plate and a small amount of defocus can simplify the experimental set-up, increase the data acquisition rate and improve resolution.
A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.
Single-particle imaging of RSC and ISW2 chromatin remodelers on DNA stretched between dual optical tweezers reveals distinctive 1D diffusion and opposing push–pull nucleosome translocation on engagement with sparse nucleosome arrays.
