The GndA microprotein promotes cell growth during heat shock in Escherichia coli

This study identifies GndA, a microprotein in Escherichia coli, which promotes cell growth during heat shock independently of its overlapping 6PGD protein.

Electrophysiological profiling of exocytosis during early-stage development of the zebrafish lateral line

The paper uses electrophysiological recordings to study exocytic properties of zebrafish lateral line hair cells during development, finding no positional variation but reduced capacitance in tail-region cells and a role for otoferlin b.

Conformations and sequence determinants in the lipid binding of an adhesive peptide derived from Vibrio cholerae biofilm

The paper investigates how a Vibrio cholerae peptide binds lipids through a β-hairpin conformation, contributing to biofilm adhesion and host colonization.

Type IV Secretion System Drives Lipid Mixing

This study shows that Type IV Secretion Systems (T4SSs) prime for substrate delivery through contact-induced lipid mixing, not requiring ATP or full complex assembly, and this mechanism applies to both Dot/Icm and RK2 T4SSs.

Vesicle docking and fusion pore modulation by the neuronal calcium sensor Synaptotagmin-1

This study shows that mutations in Syt1's C2 domains impair DCV docking but increase fusion pore size and serotonin release speed.

Polybasic patches in both C2 domains of Synaptotagmin-1 are required for evoked neurotransmitter release

This study shows that polybasic patches in both C2A and C2B domains of Synaptotagmin-1 are required for evoked neurotransmitter release, but not for spontaneous release or the readily releasable vesicle pool.
