Human P450 CYP17A1: Control of Substrate Preference by Asparagine 202 [PDF]
CYP17A1 is a key steroidogenic enzyme known to conduct several distinct chemical transformations on multiple substrates. In its hydroxylase activity, this enzyme adds a hydroxyl group at the 17α position of both pregnenolone and progesterone at ...

Perturbing dynamin reveals potent effects on the Drosophila circadian clock. [PDF]
BACKGROUND:Transcriptional feedback loops are central to circadian clock function. However, the role of neural activity and membrane events in molecular rhythms in the fruit fly Drosophila is unclear.

A functional study of AUXILIN-LIKE1 and 2, two putative clathrin uncoating factors in Arabidopsis [PDF]
Clathrin-mediated endocytosis (CME) is a cellular trafficking process in which cargoes and lipids are internalized from the plasma membrane into vesicles coated with clathrin and adaptor proteins. CME is essential for many developmental and physiological

Why enveloped viruses need cores -- the contribution of a nucleocapsid core to viral budding
During the alphavirus lifecycle, a nucleocapsid core buds through the cell membrane to acquire an outer envelope of lipid membrane and viral glycoproteins. However, the presence of a nucleocapsid core is not required for assembly of infectious particles.

Actin Dynamics Drive Membrane Reorganization and Scission in Clathrin-Independent Endocytosis [PDF]
Nascent transport intermediates detach from donor membranes by scission. This process can take place in the absence of dynamin, notably in clathrin-independent endocytosis, by mechanisms that are yet poorly defined. We show here that in cells scission of Shiga toxin-induced tubular endocytic membrane invaginations is preceded by cholesterol-dependent ...

Inhomogeneous Canham–Helfrich Abscission in Catenoid Necks under Critical Membrane Mosaicity
The mechanical effects of membrane compositional inhomogeneities are analyzed in a process analogous to neck formation in cellular membranes. We cast on the Canham–Helfrich model of fluid membranes with both the spontaneous curvature and the surface ...

VCP-dependent muscle degeneration is linked to defects in a dynamic tubular lysosomal network in vivo. [PDF]
Lysosomes are classically viewed as vesicular structures to which cargos are delivered for degradation. Here, we identify a network of dynamic, tubular lysosomes that extends throughout Drosophila muscle, in vivo. Live imaging reveals that autophagosomes

Insights Into the Antigenic Repertoire of Unclassified Synaptic Antibodies
ABSTRACT Objective We sought to characterize the sixth most common finding in our neuroimmunological laboratory practice (tissue assay‐observed unclassified neural antibodies [UNAs]), combining protein microarray and phage immunoprecipitation sequencing (PhIP‐Seq). Methods Patient specimens (258; 133 serums; 125 CSF) meeting UNA criteria were profiled;

Eukaryotic-Like Virus Budding in
Similar to many eukaryotic viruses (and unlike bacteriophages), viruses infecting archaea are often encased in lipid-containing envelopes. However, the mechanisms of their morphogenesis and egress remain unexplored.

This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...
