PLCG1 (Phospholipase C gamma1) or PLCG2 bound to the activated EPOR is phosphorylated on tyrosine residues by the kinase LYN (Ren et al. 1994, and inferred from mouse homologs). PLCG1 and PLCG2 produce inositol 1,4,5-trisphosphate which then activates calcium signaling, and diacylglycerol (DAG) which then activates protein kinase C (PKC).
