A genetically encoded photoactivatable Rac controls the motility of living cells
The precise spatio-temporal dynamics of protein activity are often critical in determining cell
behaviour, yet for most proteins they remain poorly understood; it remains difficult to …

Localized Rac activation dynamics visualized in living cells
…, GM Bokoch, MA Schwartz, S Slabaugh, KM Hahn - Science, 2000 - science.org
Signaling proteins are thought to be tightly regulated spatially and temporally in order to
generate specific and localized effects. For Rac and other small guanosine triphosphatases, …

Amiloride inhibits macropinocytosis by lowering submembranous pH and preventing Rac1 and Cdc42 signaling
Macropinocytosis is differentiated from other types of endocytosis by its unique susceptibility
to inhibitors of Na + /H + exchange. Yet, the functional relationship between Na + /H + …

An orally bioavailable chemical probe of the lysine methyltransferases EZH2 and EZH1
EZH2 or EZH1 is the catalytic subunit of the polycomb repressive complex 2 that catalyzes
methylation of histone H3 lysine 27 (H3K27). The trimethylation of H3K27 (H3K27me3) is a …

[PDF][PDF] Differential regulation of protrusion and polarity by PI (3) K during neutrophil motility in live zebrafish
Cell polarity is crucial for directed migration. Here we show that phosphoinositide 3-kinase (PI(3)K)
mediates neutrophil migration in vivo by differentially regulating cell protrusion and …
