Stimulation of phospholipase C2 by the Rho GTPases Cdc42Hs and Rac1

Abstract

Neutrophils contain a soluble guanine-nucleotidebinding protein, made up of two components with molecular masses of 23 and 26 kDa, that mediates stimulation of phospholipase C-β2 (PLCβ2). We have identified the two components of the stimulatory heterodimer by amino acid sequencing as a Rho GTPase and the Rho guanine nucleotide dissociation inhibitor LyGDI… (More)
