1 By binding to clusters of PIP2, profilin is able to inhibit the hydrolysis of PIP2 by phospholipase C gamma 1 (PLC gamma 1). Phosphatidylinositol 4,5-Diphosphate phospholipase C gamma 1 Homo sapiens
2 By binding to clusters of PIP2, profilin is able to inhibit the hydrolysis of PIP2 by phospholipase C gamma 1 (PLC gamma 1). Phosphatidylinositol 4,5-Diphosphate phospholipase C gamma 1 Homo sapiens
3 By binding to clusters of PIP2, profilin is able to inhibit the hydrolysis of PIP2 by phospholipase C gamma 1 (PLC gamma 1). Phosphatidylinositol 4,5-Diphosphate phospholipase C gamma 1 Homo sapiens
4 By binding to clusters of PIP2, profilin is able to inhibit the hydrolysis of PIP2 by phospholipase C gamma 1 (PLC gamma 1). Phosphatidylinositol 4,5-Diphosphate phospholipase C gamma 1 Homo sapiens
5 When tested for their relative abilities to inhibit the hydrolysis of PIP2 by PLC gamma 1, most of the mutants were indistinguishable from wild-type profilin. Phosphatidylinositol 4,5-Diphosphate phospholipase C gamma 1 Homo sapiens
6 Taken together with the finding that mutating residue 88 resulted in decreased inhibition of PLC gamma 1 activity, these data provide strong evidence that this region of human profilin represents an important binding site for PIP2. Phosphatidylinositol 4,5-Diphosphate phospholipase C gamma 1 Homo sapiens
