Soluble fragments cleaved from the N-terminus of PC-1 activate the PC-1/PC-2 heteromeric polycystin channel, describing for the first time that the N-terminus itself is an endogenous ligand.
p53 folding is critically dependent on zinc, and a synthetic metallochaperone rescues tumorigenic mutations that reduce p53's zinc affinity as well as thermodynamic stability.

Structure of the Ca2+ channel Orai in an open conformation provides insights into the opening mechanism and the channel's role in regulating Ca2+ entry into immune and other non-excitable cells.

The structures of secretory and dimeric IgA reveal pseudosymmetric assemblies of two antibody monomers, in which possible positions of antigen-binding fragments and accessibility to receptor-binding sites are limited.
Cryo-EM reveals the regulation of RUVBL1 and RUVBL2 AAA-ATPases by DHX34, a helicase involved in nonsense-mediated mRNA decay (NMD), and suggests mechanisms for how RUVBL1 and RUVBL2 function in NMD.
