Abstract
PC12 cells contain at least three immunologically distinct phospholipase C (PLC) isozymes, PLC-beta, PLC-gamma, and PLC-delta. Treatment of PC12 cells with nerve growth factor (NGF) leads to an increase in the phosphorylation of PLC-gamma, but not of PLC-beta or PLC-delta. This increase can be seen in as little as 1 minute. The increased phosphorylation occurs on both serine and tyrosine residues, with the major increase being in the former. This result suggests the possibility that the NGF-dependent increase in phosphoinositide hydrolysis in PC12 cells is due to selective phosphorylation of PLC-gamma by serine and tyrosine protein kinases associated with the NGF receptor.Entities:
