General description

Rac1 is a member of a RhoGTPase subfamily (Rac1-Rac4) that transduces extracellular signals from G-coupled protein receptors (GPCR), integrins and growth factor receptors to effector molecules that modulate multiple signaling pathways. While Rac1 supports the activation of MAPkinase pathways and gene activation, it’s most important functions include the regulation of cytoskeletal structures. Together with Rho (regulator of stress fibers) and Cdc42 (regulator of filopodia), Rac modulates the formation of focal adhesion (FA) complexes; membrane ruffles and lamellipodia that contribute to important cell functions related to cell attachment and movement.


Recognizes Rac1; Strong Rac1 preference with slight Rac2 cross-reactivity.

Estrogen, in addition to its genomic effects in brain, causes rapid and reversible changes to synaptic operations. We report here that these acute actions are due to selective activation of an actin-signaling cascade normally used in the production of long-term...
