Background:  Vav proteins belong to the guanidine nucleotide exchange factor family of proteins that couple receptors to Rho-GTPases. The VAV family has currently three members in mammalian cells (VAV 1, VAV 2, and VAV 3). VAV 1 contains multiple protein binding motifs, indicating a role for VAV 1 as an adaptor protein linking cell surface receptors to downstream signaling proteins. VAV 1 is exclusively expressed in hematopoietic cells and plays a significant role in lymphocyte development and antigen receptor mediated activation of NFAT and NF(kappa)B, and in more delayed responses such as the production of cytokines, including IL-2, IL-3, IFN lambda, and TNF alpha. VAV 1 is also reported to activate JNK, p21-activated kinase (PAK) and PLC lambda, implicating its critical role in calcium mobilization, and cytoskeletal rearrangement. Activation of several cell surface receptors including integrins, immune response receptors, or growth factor receptors leads to phosphorylation of VAV 1 on tyrosine residues including tyrosine 160.
