Miro1 Protects Against Acute Kidney Injury Through Modulating Mitochondrial Homeostasis via Interaction With Sirt6

Advanced Science, EarlyView.
Ischemia‐reperfusion reduces Sirt6 activity, thereby increasing Miro1 acetylation. Hyperacetylated Miro1 exhibits perinuclear distribution and degradation, thereby inducing mitochondrial dysfunction and promoting apoptosis in renal tubular epithelial cells. This pathway reveals a mechanistic link between Sirt6‐mediated deacetylation and Miro1 stability

Disparate Entry of Adenoviruses Dictates Differential Innate Immune Responses on the Ocular Surface

Microorganisms, 2019
Human adenovirus infection of the ocular surface is associated with severe keratoconjunctivitis and the formation of subepithelial corneal infiltrates, which may persist and impair vision for months to years following infection.

Dynamin inhibitors block activation of mTORC1 by amino acids independently of dynamin [PDF]

Journal of Cell Science, 2018
ABSTRACT mTORC1 plays a crucial role in protein synthesis and cell proliferation and growth. It is activated by growth factors and amino acids, including essential amino acids (EAAs), such as leucine; Leu enters cells via the Leu transporter LAT1–4F2hc (also known as SLC7A5–SLC3A2) and potentially via endocytosis.

Rocket‐Inspired Sequentially Targeted Nanotherapeutics for Mitochondrial Regulation and Inflammatory Reprogramming in Ischemic Stroke

Advanced Science, EarlyView.
A novel neutrophil‐hitchhiking, rocket‐inspired nanoplatform is developed to cross the blood‐brain barrier for sequential, spatiotemporal drug delivery. By responsive surface transformation in the ischemic penumbra, it precisely targets mitochondria to suppress Drp1‐mediated fission.

ATL2 Recruits TRAK1 to Promote Mitochondrial Transport at ER–Mitochondria Contact Sites

Advanced Science, EarlyView.
ABSTRACT Mitochondrial transport and distribution are crucial for cellular homeostasis, yet whether and how they are regulated by endoplasmic reticulum (ER)–mitochondria contact sites remains unclear. Here, we demonstrate that the ER protein atlastin‐2 (ATL2) orchestrates mitochondrial transport and distribution by promoting assembly of the transport ...

Refining Domain‐Based Prognostication in DNM1 Encephalopathy: A Mild Phenotype Associated With a GTPase Domain Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT DNM1 encephalopathy is a rare autosomal dominant genetic condition characterized by a range of neurological and developmental manifestations. The typical phenotype is severe, including profound intellectual disability, treatment‐resistant epilepsy, ataxia, and structural brain abnormalities. However, milder presentations have increasingly been

Structural inhibition of dynamin-mediated membrane fission by endophilin

eLife, 2017
Dynamin, which mediates membrane fission during endocytosis, binds endophilin and other members of the Bin-Amphiphysin-Rvs (BAR) protein family. How endophilin influences endocytic membrane fission is still unclear.

Dynamin and receptor‐mediated endocytosis [PDF]

FEBS Letters, 1996
The internalization of receptor‐bound ligands involves concentration of cell surface receptors in specialized areas of the plasma membrane and subsequent formation of clathrin‐coated vesicles. The complex process of invagination, constriction and budding of clathrin‐coated vesicles employs the coordinated actions of several proteins.

A Corkscrew Model for Dynamin Constriction [PDF]

Structure, 2007
Numerous vesiculation processes throughout the eukaryotic cell are dependent on the protein dynamin, a large GTPase that constricts lipid bilayers. We have combined X-ray crystallography and cryo-electron microscopy (cryo-EM) data to generate a coherent model of dynamin-mediated membrane constriction.
