Abstract
The regulation of Phospholipase C (PLC)delta activity remains obscure. These studies show that PLC delta(1) activity is significantly enhanc ed by both guanosine thiotriphosphate (GTP gamma S) and Clostridium bo tulinum exoenzyme C3 (C3) but not by aluminium fluoride. C3 ADP ribosy lated a 21-kDa protein in the PLC delta(1) preparation and Western blo tting identified rhoA in these samples. RhoA acts as an inhibitory mod ulator of PLC delta activity.
