Stimulation of the T-cell receptor (TCR) alters a number of
intracellular signaling pathways including one that involves protein tyrosine kinases, phospholipase C- 1 (PLC- 1), diacylglycerol (DAG), and calcium messengers. By a divergent pathway, TCR-stimulated protein tyrosine kinase activity is thought to result independently in
recruitment of the Ras activator Sos to the plasma membrane, leading to
Ras activation. Here we show that RasGRP, a Ras activator that contains
calcium-binding EF hands and a DAG-binding domain, is expressed in T
cells. A PLC- 1 inhibitor diminished activation of Ras following TCR
stimulation. Membranes from TCR-stimulated Jurkat T cells exhibited
increased RasGRP and increased Ras-guanyl nucleotide association
activity that was inhibited by antibodies directed against RasGRP.
Overexpression of RasGRP in T cells enhanced TCR-Ras-Erk signaling and
augmented interleukin-2 secretion in response to calcium ionophore plus
DAG analogues phorbol ester myristate or bryostatin-1. Thus, RasGRP
links TCR and PLC- 1 to Ras-Erk signaling, a pathway amenable to
pharmacologic manipulation.
