Tīmeklis2009. gada 18. nov. · Since Rac and Rho proteins are negative regulators of each other , it remains to be seen if the stress-induced Rac activation leads to inhibition of Rho … Rac is a subfamily of the Rho family of GTPases, small (~21 kDa) signaling G proteins (more specifically a GTPase). Just as other G proteins, Rac acts as a molecular switch, remaining inactive while bound to GDP and activated once GEFs remove GDP, permitting GTP to bind. When bound to GTP, Rac is activated. In its activated state, Rac participates in the regulation of cell movement, through its involvement in structural changes to the actin Cytoskeleton. By changing …
