A systems and molecular analysis of G protein-mediated signalling [PDF]
The ability of cells to respond correctly to signals from their microenvironment is an essential prerequisite of life. Many external signals are detected through G protein-coupled receptor (GPCR) signalling pathways, which control all aspects of ...

The GTP-Bound Form of the Yeast Ran/TC4 Homologue Blocks Nuclear Protein Import and Appearance of Poly(A)+ RNA in the Cytoplasm. [PDF]
, 1995 Ran/TC4, a Ras-like GTP-binding protein, and its nucleotide exchanger, RCC1, have been implicated in control of protein movement into the nucleus and cytoplasmic accumulation of mRNA.

The FEBS Journal, EarlyView.Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Long‐read sequencing‐based atlas of tissue‐specific expression of DNM1L transcript variants
The FEBS Journal, EarlyView.Targeted long‐read sequencing resolves full‐length DNM1L (Drp1) isoforms and reveals conserved, tissue‐specific expression patterns across human and mouse tissues. Functional assays show that Drp1 isoforms differ in their ability to drive mitochondrial fission, independent of abundance, with specific exons modulating activity.

Active Ran regulates anillin function during cytokinesis [PDF]
, 2017 Cytokinesis cleaves a cell into two daughters at the end of mitosis, and must be spatially coordinated with chromosome segregation to prevent aneuploidy.

RNF13 regulates the endolysosomal pathway through interaction with the small GTPase Arl8B
The FEBS Journal, EarlyView.The E3 ubiquitin ligase RNF13 functions as a regulatory scaffold, organizing Arl8B‐dependent complexes and tuning downstream signaling that controls endolysosomal organization and trafficking. In this model, wild‐type RNF13 associates with Arl8B on endolysosomes, whereas Arl8B (E22D/F55A) or RNF13 (L244A) variants weaken complex assembly, potentially ...

Reduction of dimensionality in Karyopherinβ1 mediated transport on FG domains [PDF]
, 2014 Many molecular transport processes in living cells proceed by facilitated diffusion in two dimensions instead of three, but how this process works remains poorly understood.

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola
Insect Molecular Biology, EarlyView.Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Immunology &Cell Biology, EarlyView.ARAP selectively regulates FcγR‐mediated signaling in dendritic cells. Loss of ARAP impairs phosphorylation of key signaling proteins, Rap1 activation, and integrin‐mediated adhesion, as well as NF‐κB p65 nuclear translocation and downstream cytokine production.
