The hierarchical assembly of septins revealed by high-speed AFM

Nature Communications, 2020
Septins are GTP-binding proteins involved in diverse cellular processes including division, polarity maintenance and membrane remodeling. Here authors use high-speed atomic force microscopy to show that assembly of septin filaments is a diffusion-driven ...

Structure‐Guided Engineering of a Cas12i Nuclease Unlocks Near‐PAMless Genome Editing

Advanced Science, EarlyView.
CRISPR‐Cas nucleases are limited by PAM requirements, restricting genome accessibility. Structure‐guided engineering of the compact Cas12i nuclease SF01 produced three variants with near‐PAMless, enabling efficient editing at diverse 5'‐NNTN‐3' sites. These nucleases expand the editable portion of the human genome more than fourfold, enabling efficient

Specific Rab GTPase-activating proteins define the Shiga toxin and epidermal growth factor uptake pathways [PDF]

, 2007
Rab family guanosine triphosphatases (GTPases) together with their regulators define specific pathways of membrane traffic within eukaryotic cells. In this study, we have investigated which Rab GTPase-activating proteins (GAPs) can interfere with the ...

A Non‐Mitophagy Activity of BNIP3L/NIX in Amygdala Glutamatergic Neurons is Essential for Contextual Fear Memory Formation

Advanced Science, EarlyView.
Contextual fear conditioning induces BNIP3L‐dependent mitochondrial fission in glutamatergic neurons of the BLA, independently of mitophagy. Loss of BNIP3L elevates Drp1Ser637 phosphorylation, thereby suppressing mitochondrial fission, compromising ATP production, and attenuating excitatory synaptic transmission.
