Building on previous work (Diao et al., 2012), we show that the mechanism by which complexin suppresses spontaneous fusion is distinct from the mechanism by which it synchronizes Ca2+-triggered fusion.
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.

Serum amyloid A proteins bind retinol with nanomolar affinity, and do so by forming oligomers that create a hydrophobic pocket that shields retinol from the aqueous environment.
Highly temperature-sensitive behavior of voltage-gated potassium channels provides a mechanistic model for how heat-activated TRP channels serve as temperature and pain sensors.
The identification of four acidic amino acids as potential calcium-binding residues in the TMEM16A calcium-activated chloride channel furthers the molecular understanding of this ion channel family.

The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.
The GEF activity of Rabex-5 is weakly autoinhibited by its CC domain and activated by Rabaptin-5 and the two proteins work concertedly to activate Rab5.
