G protein coupled activated phospholipase c
WebStudies have shown that phospholipase C-β are activated by G-protein-coupled receptors, phospholipase C-γ are activated by receptor tyrosine kinases, and phospholipase C-ε are activated by either pathway. The activation mechanisms for phospholipase C-δ, -η, and -ζ are not known. Figure 5.
