Csf1r-associated Plcg2 hydrolyzes phosphatidylcholine yielding choline phosphate and 1,2-diacylglycerol

In response to Csf1, Plcg2 (phospholipase C gamma2) associates with Csf1r, is activated by phosphorylation, and hydrolyzes phosphatidylcholine to yield choline phosphate (ChoP, phosphocholine) and 1,2-diacylglycerol (Xu et al. 1993, Bourgin-Hierle et al. 2008). Plcg2 activates pathways that enhance differentiation of macrophages (Bourette et al. 1997).
