Polyclonal Rabbit Affinity Purified B IP
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 3 is also involved in activating JNK, p21-activated kinase (PAK) and PLC lambda, implicating a critical role in cytoskeletal rearrangement. VAV 3 is inducibly tyrosine phosphorylated in response to stimulation of the epidermal growth factor (EGFR), platelet-derived growth factor (PDGFR) and T-cell receptors (TCR), enhancing its guanine nucleotide exchange factor activity in vitro. Tyrosine 173 is the regulatory phosphorylation site of VAV 3.
