VAV proteins as signal integrators for multi-subunit immune-recognition receptors
Nat Rev Immunol.
2002 Jul.
Abstract
In recent years, substantial progress has been made towards the identification of intracellular signalling molecules that couple multi-subunit immune-recognition receptors (MIRRs) to their various effector functions. Among these, the VAV proteins have been observed to have a crucial role in regulating some of the earliest events in receptor signalling. VAV proteins function, in part, as guanine-nucleotide exchange factors (GEFs) for the RHO/RAC family of GTPases. This review focuses on the role of VAV proteins in the regulation of lymphocyte development and function, and emphasizes the regulatory roles that these proteins have through both GEF-dependent and -independent mechanisms.
