A kinesin motor promotes the endocytosis of the membrane receptor LRP1 by recruiting it to caveolae.

People & Ideas

Leyser studies how plant hormones shape body plan in Arabidopsis.



The developmental and motor defects evident in flies depleted of the mitofusin Marf can be ameliorated by treatments that reduce ER stress, confirming an active role for ER stress in the observed phenotypes.


Representing a unique family of histone assembly factors, CAL1 assembles the histone H3 variant CENP-A on centromeric DNA in Drosophila.

Cell type–specific expression of the splicing regulator SLM1 provides a mechanism for shaping the molecular repertoires of synaptic adhesion molecules in neuronal populations in vivo.

To distribute the protein translation machinery throughout the cytoplasm, polysomes in the fungus Ustilago maydis associate with mobile early endosomes, resulting in long-range motility along microtubules.

PP2ARts1 controls diverse pathways that influence cell size and may link cell cycle entry to cell growth via the transcription factor Ace2.

The GPCR DP1 promotes the activity of L-PGDS, the enzyme that produces the DP1 agonist PGD2, while at the same time L-PGDS promotes the export and activity of DP1 in response to PGD2.

The motor protein KIF13B has an unconventional role as a scaffold that recruits lipoprotein receptor–related protein 1 to caveolae, thereby enhancing its endocytosis.

Graded responses to cell–cell repulsion signals mediated by Ephrin–Eph receptor interactions are specified by EphB2 cluster composition, such that the relative abundance of inactive dimers and active higher-order clusters determines the strength of the repulsive response.

PrPSc forms micrometer long amyloidic strings that can congregate in clusters and webs at the surface of living cells.


The open source MATLAB application CellGeo is a user-friendly computational platform that allows simultaneous, automated tracking and analysis of dynamic changes in cell shape, including protrusions ranging from filopodia to lamellipodia to growth cones.
