Combined spatial and enzymatic regulation of Csk by cAMP and protein kinase a inhibits T cell receptor signaling.

Abstract

Raft-associated Csk controls signaling through the T cell receptor (TCR) and was mainly anchored to Cbp/PAG (phosphoprotein associated with glycosphingolipid-enriched membrane domains). Treatment of cells with the cAMP-elevating agent prostaglandin E(2) (PGE(2)) augmented the level of Cbp/PAG phosphorylation with a concomitant increase in amounts of Csk… (More)
