http://purl.uniprot.org/citations/14993273http://www.w3.org/2000/01/rdf-schema#comment"Dok-3 is a Dok-related adaptor expressed in B cells and macrophages. Previously, we reported that Dok-3 is an inhibitor of B-cell activation in A20 B cells and that it associates with SHIP-1, a 5' inositol-specific lipid phosphatase, as well as Csk, a negative regulator of Src kinases. Here, we demonstrate that Dok-3 suppresses B-cell activation by way of its interaction with SHIP-1, rather than Csk. Our biochemical analyses showed that the Dok-3-SHIP-1 complex acts by selectively inhibiting the B-cell receptor (BCR)-evoked activation of the Jun N-terminal protein kinase (JNK) cascade without affecting overall protein tyrosine phosphorylation or activation of previously described SHIP-1 targets like Btk and Akt/PKB. Studies of B cells derived from SHIP-1-deficient mice showed that BCR-triggered activation of JNK is enhanced in the absence of SHIP-1, implying that the Dok-3-SHIP-1 complex (or a related mechanism) is a physiological negative regulator of the JNK cascade in normal B cells. Together, these data elucidate the mechanism by which Dok-3 inhibits B-cell activation. Furthermore, they provide evidence that SHIP-1 can be a negative regulator of JNK signaling in B cells."xsd:string
