An optically controlled probe identifies lipid-gating fenestrations within the TRPC3 channel, Published online: 19 March 2018; doi:10.1038/s41589-018-0015-6

A photoswitchable diacylglycerol enabled a screen that found critical TRPC3 lipid-sensing residues and identified a lateral fenestration in the pore domain that allows lipids to protrude into the permeation pathway to control channel gating.

Structural basis of the Cope rearrangement and cyclization in hapalindole biogenesis

Structural basis of the Cope rearrangement and cyclization in hapalindole biogenesis, Published online: 12 March 2018; doi:10.1038/s41589-018-0003-x

The structure of a Stig cyclase, HpiC1, reveals how it catalyzes Cope rearrangement and 6-exo-trig cyclization, including how it controls the position of electrophilic aromatic substation that distinguishes hapalindole from fischerindole alkaloids.

Regulation of apoptosis by an intrinsically disordered region of Bcl-xL, Published online: 05 March 2018; doi:10.1038/s41589-018-0011-x

Post-translational modification of residues in an intrinsically disordered region of Bcl-XL promotes interactions with its folded core and allosterically reduces affinity for proapoptotic BH3-domain-containing proteins, resulting in apoptosis.

Many thermodynamically unfavorable processes in biology are powered by ATP, the energy currency of the cell. New evidence suggests that chaperone-mediated protein stabilization may need to be added to that list.

Chaperones convert the energy from ATP into the nonequilibrium stabilization of native proteins

Chaperones convert the energy from ATP into the nonequilibrium stabilization of native proteins, Published online: 05 March 2018; doi:10.1038/s41589-018-0013-8

A nonequilibrium thermodynamic model can explain how molecular chaperones such as GroEL can use the energy from ATP hydrolysis to maintain substrate proteins in an active state, even under conditions that favor the substrate’s inactive unfolded state.

Functional TRIM24 degrader via conjugation of ineffectual bromodomain and VHL ligands, Published online: 05 March 2018; doi:10.1038/s41589-018-0010-y

Selective TRIM24 degradation is achieved by co-opting the VHL E3 ubiquitin ligase machinery. TRIM24 degradation outperforms bromodomain inhibition, with an enhanced antiproliferative effect in acute leukemia, a novel context of TRIM24 dependency.
