Study reveals that arginylation and proteolysis regulate this focal adhesion protein's function at cell–cell contacts.

People & Ideas

Khodjakov uses cutting-edge microscopy to study how the mitotic spindle is organized.



Interaction of RGS proteins with orphan GPCRs promotes signaling compartmentalization and specificity.

In breast cancer cells, growth factor stimulation of membrane protrusion was a better predictor of 3D migration than 2D motility, cognate receptor expression, or receptor activation.


Nucleostemin is a novel cell reprogramming factor that promotes self-renewal and pluripotency through effects on gene expression and cell cycle progression.

The P-site of the 60S ribosomal subunit signals to Tif6 via Elf1 during ribosomal maturation, suggesting a quasifunctional check of the integrity of the 60S subunit before the first round of translation.

The Hrd1 ubiquitin ligase plays a role in quality control of two substrates associated with the Sec61 translocon.

Actomyosin dynamics and T cell receptor signaling are tightly coupled to ensure proper dynamics and function of signaling microclusters within the immunological synapse.

Mutations in mouse intraflagellar transport–A complex genes alter Sonic hedgehog signaling because of their effects on cilia structure and on trafficking of membrane proteins into cilia.

FGFR1 cleavage by Granzyme B induces its nuclear translocation, in which it stimulates cell migration through effects on gene expression.

A proteolytic fragment of talin is regulated by arginylation and promotes cadherin-dependent cell–cell adhesion.

Reelin signaling is activated by communication between the two cell types of the collecting lymphatic vessels and promotes smooth muscle cell recruitment, which is necessary for lymphatic vessel morphogenesis and function.
