A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.

AFF4 increases the combined selectivity of HIV Tat and TAR for super elongation complexes 330-fold over P-TEFb alone.

Biochemical approaches reveal that an epigenetic histone deacetylase complex called CoREST is slow to deacetylate histone H3 lysine-14 in nucleosomes, and this inhibits demethylation of histone H3 lysine-4 by the CoREST complex.

A conserved mitochondrial inner membrane complex called MICOS works together with the mitochondrial lipid cardiolipin and respiratory complexes to direct the position, copy number and stabilization of cristae structures for efficient respiration.

The E3 ubiquitin ligase activity of polycomb repressive complex 1 is stimulated by RYBP to support a histone modification-dependent communication between polycomb repressive complexes in mice.

Ubp15 regulates the ubiquitylation of the export adaptor Mex67.

The crystal structure of Thermus transcription activation complexes containing the transcriptional activator CarD reveals a new mechanism for the activation of transcription.

Crystallography and single particle cryo-EM reveal hexameric and pentameric structures of the ExbBD energizer in the Ton system and oligomeric transition, which provides a unique working mechanism and a new vision of dynamic membrane biology.

The I_Ks potassium channel complex displays functional flexibility that depends on the ratio of its constituent KCNQ1 and KCNE1 protein subunits.

Genetic and functional studies reveal a previously unrecognized role for a transmembrane protein in glomerular filtration barrier function.
