Tec family kinases play critical roles in the activation of immune cells. In
particular, Itk is important for the activation of T cells via the T cell
Receptor (TcR), however, molecules that cooperate with Itk to activate downstream
targets remain little explored. Here we show that Itk interacts with the
heterotrimeric G-protein ? subunit G?13 during TcR triggering. This interaction
requires membrane localization of both partners, and is partially dependent on
GDP- and GTP-bound states of G?13. Furthermore, we find that Itk interacts with
G?13 via the zinc binding regions within its Tec homology domain. The interaction
between Itk and G?13 also results in tyrosine phosphorylation of G?13, however
this is not required for the interaction. Itk enhances G?13 mediated activation
of serum response factor (SRF) transcriptional activity dependent on its ability
to interact with G?13, but its kinase activity is not required to enhance SRF
activity. These data reveal a new pathway regulated by Itk in cells, and suggest
cross talk between Itk and G-protein signaling downstream of the TcR.
