GBF1 bears a novel phosphatidylinositol-phosphate binding module, BP3K, to link PI3Kγ activity with Arf1 activation involved in GPCR-mediated neutrophil chemotaxis and superoxide production
Most chemoattractants for neutrophils bind to the Gα(i) family of heterotrimeric G protein–coupled receptors (GPCRs) and release Gβγ subunits to activate chemotaxis and superoxide production. GIT2, a GTPase-activating protein for Arf1, forms a complex with Gβγ and is integral for directional sensing...
